transfer

功能

根据 Everpay 实例创建时，传递的 account, ethConnectedSigner, arJWK 参数，在转账时进行以下步骤：

• 内部构建 EverpayTxWithoutSig。
• 调用对应（插件）钱包/webauthn签名功能，生成 sig，组装 EverpayTx。
• 将信息发送给 everPay 后端服务器，进行签名验证。
• 后端服务器验证通过，更新用户资产余额。并将该笔 everPay 交易记录存储在 arweave 区块链上。

开发者可浏览 DOCS - 系统概览 - 交易 章节获取更多信息。

信息

任意 everPay 账户均支持将任意其在 everPay 上的资产转账给其他 everPay 账户，无论要转账给的 everPay 账户是 ethereum 还是 arweave 账户模型。例如：

• arweave 账户模型的 5NPqYBdIsIpJzPeYixuz7BEH_W7BEk_mb8HxBD3OHXo everPay 账户，可向 ethereum 账户模型的0x26361130d5d6E798E9319114643AF8c868412859 everPay 账户，转账 AR、ETH、USDT。
• 反之亦然。
