Klink

KLINK. smart agentic wallet on solana. the problem: every smart wallet shipping today assumes a human is in the room to approve. session keys time out, spend limits sit in a config the wallet trusts, recovery pings a guardian. none of it survives autonomous use. the april 2026 router incident that drained a $500K wallet was the preview. what we built: a wallet where the policy lives on-chain, not in a config. users write rules in a tiny DSL (max 5 SOL/day, jupiter only, no listed contracts), compile, deploy. the policy engine evaluates every transaction on-chain before it executes. x402 handles per-call settlement so every action leaves an immutable receipt. agents, bots, scripts, recurring payments all call the same wallet and operate inside the same enforced limits. the rules can't be talked out of, jailbroken, or overridden by the caller. solana itself rejects anything outside policy. why solana: sub-cent fees and sub-second finality are what make per-call policy evaluation economically viable. nothing else comes close. would love your thoughts. dropping the demo this week. checkout on @Klinkdotfun !

This is what I call @colosseum Frontier Hackathon effect!🤌🏽 Lets connect and grow together, $SOL builders! You can also shill me your Colosseum projects below👇

Final Roll Call Colosseum Frontier ends May 11th. Send me your projects below or in DMs, I’ll review and give my thoughts and feedback.

everyone is shipping AI agents. we're shipping the wallet they're supposed to use. KLINK. smart agentic wallet on solana. on-chain policy, x402 settlement, sub-cent enforcement per transaction. agents, bots, scripts all run inside limits solana itself enforces. @colosseum frontier. building in public. you can follow and checkout! @Klinkdotfun

Don't just pitch it. Build it. 👇 colosseum.com/frontier

Ok, its about that time. Show me what you're building for the @colosseum Frontier hackaton. If you don't have a project X account and building in public, what are you even doing!?

hot take: the next 10x in DeFi isn't a new yield primitive. it's wallets that act on their own and can't be talked out of their rules.we're building @Klinkdotfun on solana. on-chain policy, x402 settlement, sub-cent enforcement per transaction. agents, bots, scripts run inside limits the chain enforces. not the model. not the SDK. solana itself.the agent economy needs guardrails before it scales, not after.

Pitch your most out of the box DeFi idea

introducing klink. a smart agentic wallet, built on solana. the rails for autonomous on-chain activity exist. coinbase shipped agentic wallets on x402 in feb. BNB chain followed days later. virtuals integrated x402 and weekly transactions jumped 5x. the wallets running on top of those rails aren't ready. a thread.

9/ klink. smart agentic wallet on @solana @SolanaFndn .on-chain policy. x402 settlement. autonomous by default, contained by design.built for the colosseum frontier hackathon. demo dropping soon. @superteam @SuperteamIN

the framing matters more than the feature list."smart wallets for AI agents" is a feature riding a hype cycle."smart wallets that enforce their own rules without a human in the loop" is a primitive that scripts, schedulers, treasury bots, recurring payments, and yes, agents will all need.we're building the second one.

@solana GM GM!

There are two things people want from an AI agent: 1. Be useful without supervision 2. Never lose their money These have never been true at the same time. You either trust the model and pray, or approve every click and wonder why you bothered. The fix isn’t a smarter model.

we built something on solana. agents can use it. they can't abuse it. klink. soon.
