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).

According to @ItsDave_ADA, two of his Cardano tooling proposals have secured funding, confirming fresh builder-led development on the network (source: @ItsDave_ADA on X, Nov 9, 2025). He states the work targets closing genuine tooling gaps encountered in daily Cardano development, highlighting a practical focus on developer experience and productivity (source: @ItsDave_ADA on X, Nov 9, 2025). He pledges to deliver on the proposals, raise awareness around them, and continue building to promote innovation beyond these initiatives, signaling ongoing execution risk management by the builder (source: @ItsDave_ADA on X, Nov 9, 2025). For ADA traders, developer activity and funded execution are commonly used signals of ecosystem momentum as tracked in industry developer reports, which are often referenced to gauge network health (source: Electric Capital Developer Report 2023).

According to @ItsDave_ADA, a WASI-compiled cardano-api module was successfully loaded inside a .NET host, the GHC runtime was initialized, and a transaction handle was created via newTx(), all driven through Wasmtime without CLI or language bindings.

The author states this is a first full .NET to Cardano WASI integration that enables native .NET applications to build and interact with Cardano at the protocol level via pure interop. Source: @ItsDave_ADA on X. He reports the original JavaScript glue for cardano-wasm.wasm was removed, allowing other programming languages to load the module directly and follow the same approach.

From a trading perspective, this milestone enables direct programmatic transaction construction and protocol access from .NET, reducing reliance on external CLI tooling and expanding developer entry points for Cardano (ADA).
