According to @ItsDave_ADA, a Cardano transaction was built, signed, and submitted entirely through .NET via WASI, marking what he believes is the first such on-chain execution (source: @ItsDave_ADA on X, Nov 10, 2025). According to @ItsDave_ADA, the payment wallet was generated in .NET via WASI, manually funded, and the transaction returned the full amount as a live on-chain test (source: @ItsDave_ADA on X, Nov 10, 2025). According to @ItsDave_ADA, the transaction was signed and submitted directly through OgmiosDotnet, leveraging newly added transaction submission support (source: @ItsDave_ADA on X, Nov 10, 2025). On-chain proof was provided via Cardanoscan for transaction 98f87f9b8a95229c13ba8f4d91707527ee959bb89782e59db8b7c0ee125ff599 (source: Cardanoscan). According to @ItsDave_ADA, this validates that WASI integration works in practice and confirms Cardano transactions can be fully constructed, signed, and submitted in any WASI-compatible environment (source: @ItsDave_ADA on X, Nov 10, 2025). According to @ItsDave_ADA, the result removes barriers for wallets and transaction builders across multiple programming languages and should spur innovation where support is currently lacking, a development traders can track for ecosystem tooling expansion on ADA (source: @ItsDave_ADA on X, Nov 10, 2025).
