COSIGN

Social, on-chain

Every walletvouches forsomething.

The social layer for Solana wallets. Follow the wallets you watch, see what they hold, and trade from the same feed. No account, no password — the wallet you already have is the identity you post, message and trade with.

Connecting asks for a signature, never a transaction.

How it works

Connect, and you are already someone here.

Wallet intelligence

Every profile carries its own evidence.

A wallet profile is not a bio and an avatar. It is public blockchain information — holdings, token count, transaction history — sitting directly next to what that wallet has said. What is unavailable stays blank rather than invented.

A wallet address does not identify a person, and the interface never implies that it does.

Messaging

Talk to a wallet, not an inbox.

Search any address and start a conversation. Messages are stored off-chain so they are fast and private by default — and when something genuinely needs to be permanent, you can write that one message on-chain, after a warning that says exactly what that means.

Yeah. Watching liquidity.

Fees

2.55% platform fee. Printed before you sign.

Every trade shows the amount, the estimated network fee, the platform fee and the total — in full, on screen — before your wallet opens. There is no “0% fee” language anywhere in this product, because it would not be true.

The fee is computed on the server in integer base units. The browser never decides what you pay.

Network fees are charged by Solana and are not part of this split. Token values can fall as well as rise.

Security

The boring guarantees, stated plainly.

  • Private keys and seed phrases are never requested, handled or stored.
  • Sign-in nonces are single-use and expire in five minutes.
  • A transaction approval only opens after you confirm an amount on screen.
  • Fees are recalculated server-side. The browser never decides what you pay.
  • Messages stay off-chain unless you explicitly choose to write one on-chain.
  • All text is sanitised on write and rendered as text, never as markup.
