How Satchel checks this

Every signature this Satchel makes is recorded on NEAR before it's signed. Your browser checks each one on its own chain: a used nonce, a spent coin or an expired blockhash can never move coins again.

What it doesn't cover

  • Chains, tokens and accounts other than the three derived addresses: Bitcoin testnet4, Solana devnet, and ETH and USDC on Ethereum Sepolia, Base Sepolia, Arbitrum Sepolia and OP Sepolia.
  • What a site makes of a signed message: a message can't move coins, but a site may treat it as a login.
  • Any signature made after the purchase.
  • The honesty of NEAR's signer network.
  • Testnet4 reorgs: one confirmation can be undone by anyone mining two difficulty-1 blocks.
  • Coins another wallet later sends to an outpoint an old signature already spends (marked encumbered).

The contract doesn't run this check; this app does, by reading each chain. Buy stays disabled until it passes.

How buying works

  1. You pay
  2. One transaction moves Satchel #8 to you and pays carol.satchelhq.testnet
  3. You get everything inside
