Agreeing

Cryptographic Signatures... not pictures of signatures on PDFs.

Once the seller mints a trade and a token id is generated, the buyer is able to agree to the asset's agreement terms.

Agreement to payment terms happens through a standard web3 command that requires a cryptographic signature. Interestingly, this methodology is much more secure than traditional digital signatures.

const txHash = await buyer.invoke(
    txAssetContract, 
    "agree", 
    { 
      tokenId: toUint256WithFelts("0")
    },
    { maxFee: FEE}
  )

The token id in the example above is "0".
