    // Approve USDC for email fee
    usdc.approve(address(mailer), mailer.getFee());

    // Send email notification using prepared template
    mailer.sendPrepared(
        msg.sender,
        "reward-notification",  // template ID
        false,                  // standard mode: 10% fee only
        true                    // resolve sender name
    );
}

三つの強力な統合タイプ

スマートコントラクトから直接重要なユーザーコミュニケーションを自動化する

取引通知

リアルタイム通知ユーザー体験の向上サポートチケットの削減

成功した取引、失敗した試行、および保留中の確認について自動的に通知します。

一般的な使用例：

  • DeFi swap confirmations with slippage details
  • NFT purchase receipts with marketplace links
  • ステーキング報酬受領通知
  • ガス推定付きの失敗トランザクションアラート
  • クロスチェーンブリッジ完了状況の更新

メール送信

〜5分

あなたのコントラクトロジックから sendEmail 関数を呼び出してください。

send-emails.sol
function notifyUser(address recipient) external {
    // Approve USDC spending first (0.1 USDC for priority, 0.01 USDC for standard)
    usdc.approve(address(mailer), 100000);

    // Send priority email (recipient gets 90% fee back as claimable)
    mailer.send(
        recipient,                    // recipient address
        "Transaction Complete",       // email subject
        "Your transaction was successful!", // email body
        true,                         // revenueShareToReceiver: true = priority (90% share)
        true                          // resolveSenderToName: resolve to ENS/SNS
    );

    // Or send standard email (10% fee only, no revenue share)
    mailer.send(
        recipient,
        "Update Available",
        "A new version is ready",
        false,                        // revenueShareToReceiver: false = standard (10% fee only)
        true                          // resolveSenderToName
    );

    // Or use prepared template (priority with revenue share)
    mailer.sendPrepared(
        recipient,
        "tx-success-v1",              // template ID
        true,                         // priority mode with revenue share
        true                          // resolve sender name

高度な機能

複雑なユースケースに対応する強力な機能

条件付きロジック

複雑なオンチェーン条件に基づいてメールを送信する

例：
ポジションサイズが$1,000を超え、ヘルスファクターが150％未満になる場合のみユーザーに通知してください。

一括処理

複数のユーザーに一括でメールを送信する

例：
新しいインセンティブプログラムが開始されたら、すべてのLPプロバイダーに通知してください

テンプレート変数

取引データに基づく動的コンテンツ

例：
確認時にスワップ金額、手数料、スリッページ、およびトランザクションハッシュを含めること。

リトライロジック

失敗したメール配信の自動再試行

例：
重要な通知を最大3回まで指数関数的バックオフで再試行する
