I read the wallet flow, the pixel and the prompt. Not just the contract.
Legal counsel for crypto, artificial intelligence and data startups, in Brazil and abroad. A lawyer who has been writing code since 1996 and working in the crypto ecosystem since 2013.
To us, it's the same document.
The CLIENT shall pay 500 USDC to the CONTRACTOR within 5 days after the deliverable is approved. Late payment shall incur a 2% penalty on the amount due. If the CLIENT does not respond within 10 days, the deliverable shall be deemed approved.
// Clause 4 — payment for the deliverableuint256 constant VALOR = 500e6; // 500 USDCuint256 constant PRAZO = 5 days;uint256 constant MULTA_BPS = 200; // 2%uint256 constant ACEITE = 10 days; function pagar() external onlyContratante { uint256 devido = VALOR; if (block.timestamp > aprovadoEm + PRAZO) devido += VALOR * MULTA_BPS / 10_000; usdc.transferFrom(contratante, contratado, devido);}function aceiteTacito() external { require(block.timestamp > entregueEm + ACEITE); aprovadoEm = entregueEm + ACEITE;}
On paper, a misplaced comma becomes a dispute. In a smart contract, it becomes a bug that no one can revoke. That is why I read both versions, and write each one with the other in mind.

In crypto, the rule is to verify rather than trust. The same applies here: every credential has a public source.

Lucas Lopes Galvão
Lawyer and programmer. I wrote my first code at age 9 and opened my first law office in 2013, the same year I entered the crypto ecosystem.
I hold a master's degree in European and German Law from UFRGS and PUCRS, with research at the European Parliament in Brussels and a dissertation on privacy on the blockchain. Since 2020, I have represented a group of Chinese companies in Brazil, including an exchange and a prediction market.
Today I divide my time between the firm and building products: I am COO of ASH Soluções em AI, CTO of NextPro and founder of Complian.cc.
