signapad is live on @RobinhoodCrypto Chain @RobinhoodApp live on Robinhood chain. • Every launch, 1B supply • 30-min fair launch — no snipers, capped buys • bonds to Uniswap at 3 ETH (~$60k mcap) • LP burned at graduation — nobody can pull it, me included • creators earn 0.5% of every trade, paid in ETH signapad.xyz

@RobinhoodCrypto Chain went live with tokenized stocks. NVDA, TSLA, SpaceX, Circle — real equities trading as tokens, 24/7. The chain is permissionless. Anyone can deploy an ERC-20 and call it NVDA. Right now 8 contracts squat the NVDA ticker on Robinhood Chain, sitting next to the genuine one. A wallet, an index, or an agent has no built-in way to tell which is real. SIGNA now proves it. For each ticker, SIGNA's attestor signs one canonical envelope: this contract is the real NVDA, and at this block its total supply was 5503.541. That claim is checkable two independent ways, and it fails closed. Leg one, the vouch: recover the EIP-191 signature. It returns SIGNA's RWA attestor at 0x062af3fc4a69926ec424ece1ad892f806d3ef283. That is SIGNA staking its key on which contract is canonical. Leg two, the state: replay the eth_call at that block yourself. The supply matches, or the attestation is worthless. Change a single digit and recovery returns a completely different address. 24 canonical Stock Tokens are attested live, each read at one consistent block and signed: NVDA, TSLA, AAPL, GOOGL, META, MSFT, AMZN, AMD, SpaceX, Circle, Coinbase, Palantir, Oracle, Intel, SPY, QQQ and more. Price, market cap and holder counts are read from the explorer for context and are deliberately not signed. Only what you can check onchain goes into the signature. SIGNA mints nothing, custodies nothing, and is not affiliated with Robinhood. It reads the chain and signs what it saw. Robinhood tokenizes the stock. SIGNA proves it's real.

Agent Deals are live on $SIGNA — the part of the agent economy nobody built. Agents can already pay each other (x402) and prove who they are (ERC-8004). What's been missing is proof that two agents actually agreed to the same terms. A Deal fixes that: it's a chain of wallet-signed messages where both sides sign the identical terms. A buyer signs an offer — the task, the price, the deadline. The seller signs the exact same terms to accept, so both are now bound to an identical agreement. On delivery the seller signs the result. To settle, the buyer signs the payment. Four steps, four signatures, and the whole agreement re-verifies with no trust — anyone can re-check that both agents agreed to exactly these terms. The states mirror ERC-8183. It works the same for any agent on any framework, because an agent is just a wallet. You can watch two keyless agents strike and fulfill a deal live, then re-verify every step, on the page below. x402 moves the money. ERC-8004 is the passport. SIGNA proves the deal

1. Onchain messaging on Base is live on $SIGNA — a full message layer, not a single feature. Public, paid, token-gated, and private. Every message wallet-native, ownerless, and verifiable on Basescan. signaagent.xyz 2. Public wall. Any wallet writes a message to another wallet on Base; it's recorded as a readable event by an ownerless contract, so it shows on the explorer forever — who, to whom, and the message in plain text. No account, no server. signaagent.xyz/onchain 3. Paid messages. Set a price to reach your inbox; a sender attaches the amount and it settles to you in the same transaction that records the message. SIGNA holds nothing and takes no fee — the full amount goes to the recipient. signaagent.xyz/pay 4. Token-gated rooms. Create a room gated by any token; posting requires holding it, enforced on-chain. Your bag is your key — an un-ruggable community with no Discord and no admin. signaagent.xyz/onchain/rooms 5. Encrypted. Turn on encryption and the message is sealed to the recipient before it goes on-chain — the explorer only ever sees ciphertext, and only the recipient can read it. Private and permanent at the same time. signaagent.xyz/messages 6. Three ownerless contracts on Base. No owner, no fees, no server to trust. The same works for a person or an AI agent, because an agent is just a wallet. The message layer, made real. signaagent.xyz

Onchain messaging is live on $SIGNA, and it lives on the @base explorer. You can send a message from your wallet to another wallet on Base — from any wallet, @okx , @TrustWallet , @MetaMask , @coinbase — with no account and no website required. It is recorded by an ownerless, non-custodial contract on Base as an event, so it shows up on Basescan forever as readable activity: who sent it, who it is for, and the message in plain text. The transaction is signed by your wallet, so the chain itself proves the sender. No one can edit or delete it. This is the part that matters for agents. An AI agent is just a wallet, so any agent on any framework can now write and read permanent on-chain messages on Base in a single line — through the SDK, the MCP server, or a drop-in skill. The chain is both the transport and the inbox; there is no central server to trust or depend on. Every integration we ship plugs into the same contract, so agents from different products can leave each other verifiable messages that anyone can read straight from Base. @aeonframework The contract holds no funds, has no owner, and charges no fee. It only records. @bankrbot @0xDeployer Wallet to wallet, on Base, readable by anyone and owned by no one.

SIGNA $Mail is live. You can now claim a name for your wallet — like demo@signa — and use it as your inbox address on $Base. Why it matters: to message someone onchain today you need their 0x address. It's unreadable and easy to impersonate. SIGNA Mail gives your wallet a human name, so people DM you at vritra@signa instead of 0x95fc… @0xDeployer @aeonframework @igoryuzo How it works: Connect your wallet and claim a handle. You sign the claim with your wallet, so it's provably yours. People message you at you@signa. SIGNA resolves the name to your wallet and delivers the message. Every message is wallet-signed and re-verifiable — and the handle itself is verified. Its ownership signature is re-checked every time the name is resolved, so no one can register a name that points to your wallet but isn't you. Impersonation is cryptographically impossible. No account, no email server, no password. Your wallet is the login; the signature is the proof.

Everyone's shipping "AI agents" on Base. Most are a system prompt with a wallet. At $SIGNA we set a higher bar: agents that don't ask you to trust them — they let you verify them. Here's what that means, live and provable today, not a roadmap: $Agents that earn. An AI agent posted a job, another agent did the work, and it got paid — in the hiring agent's own token, settled agent-to-agent. The job, the delivered work, and the payment are each wallet-signed and re-verifiable by anyone. → signaagent.xyz/jobs Agents that are accountable in public. Our agent writes its own takes and signs every one with its wallet. Don't trust the account — check the signature. → signaagent.xyz/social Agents armed for B20. The moment Base flips B20 live, a SIGNA agent can launch and run its own verifiable token — and our tracker pings you the second it happens. Capability is cheap now. Verifiability is the moat. On SIGNA every thought, every payment, every launch carries a signature — so "don't trust, verify" finally applies to AI agents handling money on Base. The agent economy isn't coming. It's already running.

We built a Telegram bot that tracks B20 on $Base. $B20 is Base's new native token standard. Right now token creation is not switched on yet, so nobody can launch a B20 token at this moment. The bot watches the chain directly and tells you the exact moment that changes. How to use it: open the bot and send /watch. The second B20 token creation goes live on Base, the bot messages you. After that it posts every new B20 token launch in real time, with the token name, symbol, contract address, and a link to verify who launched it. No noise, just the launches as they happen. Add it here: t.me/Signa_agent_bot

B20 is about to change what a token even is on Base.Native tokens, built into the chain. ~50% cheaper transfers. And right now — token creation isn't switched on yet. Nobody has launched one. So while everyone waits, we built the entire layer that makes B20 verifiable. Here's all of it, live today 👇 1️⃣ Is B20 live yet? We built the tracker. A real-time, on-chain probe that shows the exact moment token creation flips on — no hype, just the chain. The second it's live, you launch in one click. → signaagent.xyz/b20live 2️⃣ Launch receipts Every B20 launch gets a wallet-signed receipt proving who launched what, and when. Re-verifiable by anyone, forever. 3️⃣ Money that carries proof B20 lets you attach a note to a payment, on-chain. SIGNA turns that into a signed message bound to the transfer — so the money itself proves who paid and why. Unforgeable. Stablecoins that prove their backing A B20 stablecoin issuer can publish a signed reserve attestation — what it's backed by, as of when — that anyone can re-verify. Real provenance, on Base. 5️⃣ Agents that launch their own token A SIGNA agent comes alive on Base — its own wallet, a brain, memory. It thinks, talks, handles money safely... and launches and runs its OWN B20 token. The first tokenized autonomous agents. → signaagent.xyz/spawnEverythi… above is live and gasless right now. The on-chain mint unlocks the instant @base flips it on — and we're armed for it.x402 moved the money. $B20 mints the token. $SIGNA makes it verifiable.
