The button opens X with your code written. Post it as it is, then paste the link to your post. We only read the post. Verified accounts only, so one person is one seat. Optional: the bridge works without it.
1 · POST YOUR CODE ON X →Not our word. A public verification.
Every transfer comes with a proof that anyone can check on-chain. The transfer's events fold into the twig for their chain, the twigs fold into the root, and the root is sealed publicly. Checking it needs the proof and nothing from us.
New chains, new bridges and what the record unlocks are posted there first.
FOLLOW ON X →Join first and you get a page of your own to share: your transfers, each with its proof.
SHARE THE BRIDGE →Access is opened from this list, in order: the most GRID on the bridge record first, and whoever qualified earlier wins a tie. The list is public and nobody is added by hand.

GRID is earned only for things that can be verified: joining with your X account, a transfer the service saw delivered, a new destination chain. Posts are not paid: a proof you post goes on the record as a fact and earns nothing. The record is public, and more GRID on it is an earlier place on the whitelist.
A contract that checks the Internet Computer's own certificate of its ICP ledger: the NNS threshold signature (BLS12-381, through the EIP-2537 precompiles), the state-tree witness down to the ledger's certified tip, and the chain of ledger blocks behind it. No relayer is trusted; anyone can submit a certificate. It has no owner and no admin and sits at the same address on every chain.
Live on Base, Arc, Robinhood Chain and Taifoon mainnet with a real NNS certificate verified on each chain. Read it with latestTip(), isLedgerBlock(bytes32); extend it with submitTip and proveAncestors.
A gate on each chain (0x0B55d43D…31f7eF; Taifoon mainnet 0xbe505180…7B8590) mints wrapped ICP against a proven ledger deposit and burns it for a release. The custody canister dkafq-4aaaa-aaaaj-a6ysq-cai holds the ICP and releases it only against a burn every configured endpoint reports in a finalized block. Minting is open on all four gates; the first deposit, mint, redeem and release ran on Base on 2026-10-03.
The same light client as a Solana program (BLS12-381 syscalls) is built and tested on the runtime, not deployed.
To use it, pick Internet Computer as FROM or TO in the bridge above, with Base, Arc or Robinhood Chain on the other side. The route shows up there with its cost and time, and the send panel gives you your deposit account.
How it works, with every transaction hash: the write-up.
