Chainflow Tools

Chainflow's x402 facilitator verifies and settles x402 payments on Solana. x402 is an open payment standard that lets AI agents and applications pay for API access in USDC on a per-request basis, without accounts or API keys.

Settlements are submitted through Chainflow's own staked Solana validator. Solana's stake-weighted Quality of Service (SWQoS) gives transactions from staked validators priority access to the leader, which helps settlements land when the network is congested.

You don't need an API key or a wallet to use it. Sui and more PoS networks are on the roadmap.

chainSOL is Chainflow's liquid staking token on Solana. It lets you stake SOL with an independent validator and keep it usable in DeFi, for example as collateral on Loopscale.

Every epoch, Chainflow returns 100% of the inflation commission and MEV earned on chainSOL's stake to the pool. Each return is an on-chain transaction you can check on the chainSOL dashboard.

chainSOL runs on Sanctum's stake-pool program and is governed by an 11-member multisig.

Chainflow runs RPC nodes on Solana and Sui alongside its validator infrastructure. We offer reliable, low-latency, validator-grade RPC access to teams building community-focused applications (dApps), on a project-by-project basis.

Nakaflow tracks the Nakamoto Coefficient in real time across proof-of-stake networks. The Nakamoto Coefficient is the smallest number of independent parties that together control enough stake to halt a network.

Many operators run several validators, so counting validators overstates decentralization. Nakaflow groups validators by the operator that runs them, using on-chain stake and published operator data. The full methodology is documented and open on the site.

A security-focused toolkit for signing Solana transactions in an air-gapped environment, so private keys never touch a networked device. It's designed for validator operators and treasuries managing high-value keys.

Transactions are constructed on an internet-connected machine, transferred to an isolated offline signer, and broadcast once signed, keeping private keys off networked devices entirely. It supports SOL and SPL transfers, the full stake account lifecycle, and SPL Governance voting.

Read the deployment notes before using it beyond testing.

An open-source monitoring dashboard for validator operators, providing reporting, alerting, and performance visibility for Solana and Cosmos validators.

A monitoring service that tracks validator commission rate changes across the Solana network. Commission changes affect delegators' staking rewards, so the monitor flags increases as they happen.

Monthly validator-led calls covering network governance, technical updates, and community topics. Held on the 4th Thursday of each month. Open to the public.

A grassroots coalition of independent validator operators advocating for decentralization across Proof-of-Stake networks. Chainflow is a founding member.

Co-produced by Chainflow's Chris Remus and Throbac Labs, covering the behind-the-scenes work of independent validators.
