}Operações em lote
Este endpoint suporta operações em lote: você pode executar várias operações de escrita em contratos em uma única chamada de API. É especialmente útil para padrões comuns como “approve + deposit”.Formato da requisição em lote
Para executar várias escritas, use o arraycalls:
{
"calls": [
{
"address": "0xTokenContract...",
"method": "approve",
"parameters": ["0xSpender...", "1000000000000000000"],
"abi": [...],
"reference": "approve-tx",
"metadata": { "step": "approval" }
},
{
"address": "0xProtocolContract...",
"method": "deposit",
"parameters": ["1000000000000000000"],
"abi": [...],
"reference": "deposit-tx",
"metadata": { "step": "deposit" }
}
],
"code": "123456"
}
Formato da resposta em lote
As respostas em lote incluem os arrayssuccess e errors:
{
"message": "Batch contract write initiated successfully",
"statusCode": 200,
"data": {
"success": [
{ "id": "tx-uuid-1", "hash": "0x...", "status": "pending", "reference": "approve-tx" },
{ "id": "tx-uuid-2", "hash": "0x...", "status": "pending", "reference": "deposit-tx" }
],
"errors": []
}
}
Esquema de cada item do lote
| Parâmetro | Tipo | Obrigatório | Descrição |
|---|---|---|---|
| address | string | Sim | Endereço do contrato inteligente |
| method | string | Sim | Nome do método a ser chamado |
| parameters | array | Não | Parâmetros do método (padrão []) |
| abi | array | Sim | ABI do contrato |
| reference | string | Não | Referência própria para rastreamento |
| metadata | object | Não | Metadados próprios |
Tratamento de erros
As operações em lote seguem um padrão de sucesso parcial:{
"data": {
"success": [...],
"errors": [
{
"index": 2,
"method": "transfer",
"error": "Insufficient balance"
}
]
}
}
- As operações são executadas sequencialmente
- A falha de uma operação não interrompe as seguintes
- Verifique os arrays
successeerrorspara saber o resultado geral
Regras de validação
| Regra | Valor |
|---|---|
| Tamanho máximo do lote | 20 operações |
| Tamanho mínimo do lote | 1 operação |
| 2FA obrigatório | Sim |
Casos de uso
- Approve + Deposit: autorize o gasto do token e deposite em uma única chamada
- Transações de várias etapas: encadeie várias chamadas de contrato para operações DeFi
- Interações com protocolos: execute interações complexas de forma atômica
