There is a specific type of asset designed to stay as steady as the cash in your pocket. These are called stablecoins, and they are currently at the center of a major policy shift in the UK.
As an example if Bitcoin is like digital gold, stablecoins are like digital dollars or digital pounds. Assets like USDC or USDT are designed to be "pegged" 1:1 to a sovereign currency, usually the US Dollar. They aren't meant for "mooning" or speculation; they are built to be a secure, liquid way to save, pay, and earn on-chain without the price swings of traditional cryptocurrencies.
Anyone with a Revolut account in the UK will notice some recent changes namely the pound-pegged stablecoin. As of May 2026, Revolut is one of four firms selected for the Financial Conduct Authority's (FCA) Stablecoins Regulatory Sandbox, which allows for testing of digital assets in a controlled, "real-world" environment.
Why This Matters to Everyone (The "Tax Trap")
Currently, HMRC does not recognize stablecoins as "money". Instead, they are treated as property, meaning every single time you use them, you might be triggering a Capital Gains Tax (CGT) event.
HMRC is Asking for Our Help
In a rare move, HMRC is proactively seeking evidence from the market on how to reform these rules. They are considering founder-friendly options, such as full tax exemptions that would treat stablecoins like the cash you hold in a bank account, or a "de minimis" threshold so small daily payments don't need to be reported.
This is a critical moment for the UK to build a "smarter tax design" that actually encourages innovation rather than stifling it with paperwork.
HMRC is actually being helpful here
Worth saying explicitly because it's easy to miss: HMRC is the only major tax administration globally that's proactively trying to reform stablecoin taxation.
They're not raising new taxes through this CFE, they're exploring whether to remove tax burden, not add to it.
The options on the table look genuinely founder-friendly:
The deadline to submit evidence to HMRC is 7 May 2026. If the industry does not provide concrete, sensible feedback, the new rules will be drafted by people who don't have to live with the consequences.
How to get involved:
You can also Tag u/whaleicorn in comments who works specifically in policy and is a SuperteamUK Growth developer.
As the title states. Been looking over documentation and says it should be there under settings in a section called "Developer API". But i don't see this? is there a setting or account age issue for this?

Over the weekend the KelpDAO exploit on a LayerZero powered bridge wiped out roughly 116,500 rsETH, around 290–300 million dollars, in what is already being called the biggest DeFi hack of 2026.
The scary part is not some obscure solidity bug, but the fact that the attacker tricked the cross chain messaging layer by compromising the verifier setup, then pushed forged packets that the bridge happily treated as valid withdrawals. KelpDAO was reportedly running with a single verifier instead of a hardened, redundant configuration, so once that was poisoned there was no second opinion on what “truth” was across chains.
This is EXACTLY the class of failure that Solana devs and users should be thinking about when we talk about “interoperability”.
This is not unique to LayerZero. It is a pattern we have seen again and again with lock and mint bridges, multisig bridges, and generic messaging systems: you are ultimately trusting keys, off chain infrastructure, or a small group of operators, not the actual consensus of the chain you are talking to.
On Solana we should not be content to repeat that design.
Nolus today is an appchain in the Cosmos ecosystem focused on asset backed, fixed rate leverage, already plugged into multiple DEX liquidity hubs through IBC and interchain accounts. Instead of cloning the same protocol across ten chains, Nolus runs one chain and reaches out to other ecosystems through native interoperability, something which is completely unknown to any ecosystem apart from cosmos... until now.
The missing piece for Solana has been a truly trust minimized way to speak IBC. That is what IBC Solray is about. It is a protocol that brings the full IBC client architecture to Solana so that Solana and Nolus (and other IBC chains) can verify each other directly, not through wrapped assets or multisig custodians.
A few key points from what we have already shared with our community:
Full IBC client architecture on Solana
Solray implements the IBC side needed for Solana to understand the state of a counterparty chain using a client based model instead of trusting an external bridge committee.
Nolus as “remote” Solana smart contract
Nolus remains an appchain but can behave like a Solana native program from a user perspective: open leveraged positions, interact with Solana liquidity via Jupiter, pay gas, etc., while risk logic and accounting live on Nolus.
Liquidity routing instead of asset fragmentation
By using IBC and interchain accounts, Nolus can tap liquidity hubs like Osmosis and Solana DEXs directly, instead of spawning yet another wrapped version of every asset on every chain.
The end game is that a Solana user can access Nolus’ products BUT this is only the beginning before also bringing IBC connection to Ethereum (apart from cosmos). Then the whole web3 space will be a much safer place in terms of cross-chain interoperability.
IBC has been live in production across more than one hundred Cosmos chains since 2021 and has not had a protocol level exploit. There have been chain bugs and application bugs, but the core transport and verification layer has held up because its security assumptions are simple: each chain verifies the other chain’s consensus state via a client and only accepts packets that can be proven against that state.
In practice that means:
If the KelpDAO bridge had been built as a pure client verified IBC style connection, an attacker would have needed to actually break Ethereum or the other chain’s consensus to forge those rsETH withdrawals, not just compromise some verifier keys or infra. That is a very different threat model than “hack this one verifier and the bridge empties”.
IBC is not magic and it is not risk free, but its failure cases are aligned with the chains themselves, not with extra trusted parties bolted on the side. That is why a lot of us consider it the only real interoperability standard that has been battle tested in production for years rather than yet another experimental bridge pattern.
What is the foundational philosophy for building meaningful communities?
In an era where our feeds are often dominated by "dopamine-engineered slop" and content designed purely for engagement, IRL events are the last defence against "brainrot".
Solana Run Club are taking this philosophy to the pavement. Whether you are a founder, a developer, or just someone looking to escape the screen, the Solana Run Club is where everyone shift from "broadcasting" to actually joining the conversation and a good run.
Where: London, Hyde Park
When: Sunday, April 19th 2026
The Plan:
Authentic brand participation yields tangible results, and building a community creates long-term loyalty that traditional advertising simply cannot buy. This is your chance to "touch grass," meet the humans behind the projects, and build your relationships that define the UK ecosystem.

If you are a developer or trader managing significant on-chain value, you’ve likely accepted a fundamental trade-off: the convenience of hardware wallets versus the persistent risk of long-lived private key storage. Coldstar is a CLI-first cold wallet system that challenges this model by removing the need for permanent trusted hardware entirely. Also Coldstart IS coming to mobile soon!
Traditional hardware wallets rely on secure elements that store private keys for their entire lifetime, creating a persistent physical attack surface and supply-chain risk. Coldstar shifts this trust anchor to open-source software and volatile memory. It transforms any standard USB drive into a disposable signing medium where keys are only decrypted in RAM for the exact duration of a transaction signature.
Coldstar’s architecture is built on three core pillars of data protection:
Encrypted at Rest (The Digital Vault): Think of your private key as a secret message that is never written down in plain English on your USB. Instead, Coldstar uses advanced "scrambling" math (Argon2id and AES-256-GCM) to turn your key into unreadable gibberish the moment it’s saved.
This means if someone physically steals your USB drive, they cannot see or use your key because it is effectively locked in a vault that only your password can open
Memory Isolation with mlock() (The "No-Paper-Trail" Rule): Computers often move data from "fast" temporary memory (RAM) to "slow" permanent storage (your hard drive) to save space, creating a "swap file" that could be found by hackers later.
Coldstar uses a command called mlock() to "pin" your key in RAM, strictly forbidding the computer from ever writing that sensitive data onto the hard drive. This ensures your key never touches permanent storage while it is being used to sign a transaction.
Immediate Zeroization (The Digital Shredder): Coldstar follows a "need-to-know" policy where your secret key only exists in an usable form for the tiny fraction of a second it takes to sign your transaction. The moment the signature is complete, the system acts like a digital shredder, overwriting the key’s memory with nothing but zeros (turning 0x42... into 0x00...). This "zeroing out" ensures that even if a hacker managed to look at your computer’s memory a millisecond later, your key would already be gone
Coldstar is specifically built for automation-native environments. While consumer wallets prioritize GUI convenience, Coldstar is designed for:
CI/CD Pipelines & Headless Environments: There is no GUI dependency or background daemon, making it ideal for automated trading systems or air-gapped workflows.
Full Scriptability: Because it is CLI-first, you can integrate it into custom Python or Rust-based tools without the "manual click" friction of traditional devices.
Asset-Agnostic Design: While optimized for the Solana network’s speed ($0.00025 fees and 400ms finality), it supports custom program instructions, staking, and SPL tokens under the same security model.
As we move toward an economy of AI agents paying for their own compute via protocols like x402, we need signing infrastructure that is fast and autonomous. Coldstar provides the rails for this shift, allowing machine-to-machine transactions to occur securely without a human needing to press a physical button on a device.
What's more Coldstart is coming to mobile! You can sign up here also for some free merch if you are one of the first 200 to join.
