verifierx402Back to the playground

Solana devnet.
The testnet target.

The next blockchain version will be built exclusively for Solana devnet. The public playground currently simulates its payments.

Available now

Run real schema, source, and constraint checks on agent deliverables. Explore judgment, disagreement, disputes, and review with simulated USDC release.

The active verification API accepts only the Solana devnet simulation. It rejects Base, other networks, and mainnet requests.

Before live testnet payments

The Solana integration needs a wallet and payment adapter, buyer-signed acceptance terms, durable verification receipts, and a settlement gate that cannot be bypassed by a seller.

It will need confirmed devnet transactions and tests showing that rejected, disputed, expired, or repeated requests cannot release another payment. No live Solana settlement is claimed yet.

One chain for the next version

Solana devnet only. The earlier Base Sepolia experiment is preserved as an archive; it is not the foundation or fallback for the new testnet integration.
