add anvil local to your wallet

One click and your wallet (MetaMask, Rabby, etc.) gains the local anvil chain (chainId 31337) at http://127.0.0.1:8545. After that, /dash and the trade panels can submit transactions to your local 1SAT deploy.

add and switch

If your wallet has never seen this chain, this triggers wallet_addEthereumChain. If it already knows the chain, it triggers wallet_switchEthereumChain instead. Approve the prompt that pops up.

manual setup, if the button is sad
