Send to a handle

Pay a handle before its owner has ever heard of Post. Your wallet signs a plain ETH transfer to the Post wallet with post:@handle in the calldata. Post reads the hash from chain and writes the claim.

NetworkRobinhood Chain, chain id 4663

Your wallet signs it. Post reads the hash from chain and credits the handle.

Any EVM browser wallet signs this, MetaMask or Rabby on a desktop, the in-app browser of a wallet on a phone. Chain 4663 does not have to be set up by hand: on connect, Post asks the wallet to switch to Robinhood Chain, and to add it if the wallet has never seen it. The ETH being sent, and the gas that moves it, both live on chain 4663.

What happens next

1Your wallet signs

A plain ETH transfer to the Post wallet. The handle is the calldata, so the transfer carries its own address label.

2Post checks the hash

The server reads the transaction and its receipt. It has to be addressed to the Post wallet, it has to have succeeded, and the calldata has to decode to a real handle. Nothing from the browser is trusted except the hash.

3It lands in the ledger

The ETH is priced at the Chainlink ETH/USD feed and written against that handle, ready to claim. The same hash posted twice returns the first claim.

4They claim it

The owner signs in with one post, sees it on the Claims page, and picks any supported asset to receive it as.

A send is final. Once it is on chain, Post cannot reverse it, refund it or point it at a different handle. The Post wallet holds what is sent until that handle signs in and claims it, with no expiry and no sweep, so it waits as long as it has to. The wallet address is published by /api/status and every transfer in and out is on Blockscout. That same endpoint publishes the per-transaction cap, $500 on this deployment: a claim settles whole, in one transaction, so a single send worth more than the cap cannot be paid out and the owner is refused with tx-cap. Send a larger amount as several smaller transfers to the same handle.
