FAQ — Matriz de Taxas de Saque por Rede (Arbitrum, Base, Solana, Lightning vs L1)
Does bridging ETH from Ethereum L1 to Arbitrum or Base trigger a taxable swap in Brasil?
If you receive a distinct wrapped token or swap assets, it may be treated as a disposal under Permuta cripto-a-cripto conta para o volume mensal de R$ 30.000 na IN 1888 e é considerada alienação tributável pela Receita Federal (Solução de Consulta Cosit nº 214/2021); withdrawing directly from your exchange over Arbitrum or Base avoids an on-chain bridge transaction.
Can network gas and exchange withdrawal fees be deducted on Instrução Normativa RFB nº 1.888/2019, GCAP (DARF 4600), Declaração Anual IRPF (Grupo 08) & Lei 14.754/2023 (Offshore 15%) (Brasil)?
Yes—Receita Federal do Brasil (RFB) rules allow adding acquisition fees to your cost basis and deducting disposal fees from gross proceeds.
