FAQ.

Any EVM wallet supported by RainbowKit — that covers MetaMask, Rabby, and Rainbow out of the box, plus other injected wallets. The connect button auto-detects what you have installed.

Native ETH and USDG (Global Dollar, an ERC-20 stablecoin by Paxos) at launch. More ERC-20 tokens are on the roadmap — each needs per-token approval and transfer handling on both ends of the flow.

CLAIMA itself takes nothing. You pay Robinhood Chain gas, which is very cheap on an Arbitrum Orbit L2. For an ETH link the burner wallet pays its own gas at claim, out of the locked balance, so the receiver pays nothing. For a USDG link the burner signs an EIP-3009 authorization off-chain and the recipient submits it, paying a small gas fee themselves — the burner never needs ETH.

Yes — if you still have the URL and the password, open the link yourself in your own browser and claim the funds back to your own wallet. There's no "cancel link" action; the temp vault releases to anyone who proves the secret.

A future on-chain escrow contract will allow sender-side reclaim without needing to remember the password. For now: track your links in /c/mine and don't lose passwords.

Same threat model as sending a private key in plaintext — anyone who intercepts that message can claim. Don't do this for anything beyond demo amounts. Use two channels.

The flows render on mobile, but wallet connectivity depends on which wallet you use. MetaMask, Rabby, and Rainbow all ship mobile apps with in-app browsers that connect successfully. Cross-app WalletConnect deep linking is on the roadmap.

Because we don't need one. Every operation is browser-side or on-chain. No backend means no database to leak, no service to maintain, no subpoena to receive, and no extra trust surface for you to evaluate.

In your browser's localStorage, under the key claima.history.v1. We never read it. Clearing site data, switching devices, or using incognito will wipe it. You can manually clear it from /c/mine.

The default RPC is the public Robinhood Chain endpoint for the active network (rpc.mainnet.chain.robinhood.com on mainnet). If the operator (you, if you self-host) configures an Alchemy URL in environment variables, all read and write calls go through there for higher rate limits. On testnet, funding comes from the faucet at faucet.testnet.chain.robinhood.com rather than the RPC.
