An introduction to Lit Actions and PKPs

Mint PKPs here

To use, pass a valid Cosmos address, an amount, and fee. The fee must be hardcoded since the transactions cannot be simulated with PKPs.

  const txRes = await pkpCosmosSigner.sendTokens(
    recipientAddress
    [{denom: "uatom", amount: "100000"}],
    {
      amount: [{denom: "uatom", amount: "1000"}],
      gas: "100000",
    }
  );
  
  console.log('txRes', txRes)
