CCTP 现在支持快速转账（Fast Transfers）的前置费用支付。开发者现在可以在源链的原生 gas 代币或 USDC 中提前报价并收取费用，而不是在目标链上从转账的 USDC 中扣除协议费用。因此，开发者可以简化跨链转账的费用处理，用户可以收到预期的 USDC 金额。

可预测的转账和简化的费用处理

通过在执行转账之前处理费用收取，此次对 CCTP 快速转账的更新解决了跨链应用的三个核心挑战：

• 可预测的转账金额： 终端用户可以收到预期发送的 USDC 金额，避免目标端扣费和支付或钱包流程中出现意外的净额。
• 通过报价 API 的一揽子报价： 报价 API 在支持的链上抽象了费用计算，将快速转账和转发费用捆绑为单个报价。集成方无需再构建自定义基础设施来独立计算多协议费用。
• 灵活的费用收取： 费用可以以源链的原生代币收取，而不会侵蚀或触碰正在转移的 USDC 余额。

如何开始

对于 所有 EVM 链上的 USDC 转账，CCTP 现在提供预付费用功能。虽然当前不支持从 Solana 发起的转账，但支持转账至 Solana。

要实现预付费用，集成方可以查询报价 API 以获取费用报价。
