# NEIRO Payment Network (NPN) > Solana transactions with gas paid in NEIRO. Independent Kora operators supply SOL and receive NEIRO. Clients discover signed terms onchain and call operators directly; no router is required. ## Choose one starting point - [Human: choose how to run an operator and copy the agent brief](https://github.com/bropump/neiro-payment-network#set-up-your-operator) - [Agent running an operator: AGENTS.md](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/AGENTS.md) — the single setup procedure, including required evidence for completion. - [Client / builder: BUILD-WITH-NEIRO.md](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/BUILD-WITH-NEIRO.md) — use an existing operator with your wallet or application. No operator installation required. This file is an index. Follow your selected procedure; open references when it links to them. ## References - [Host, RPC and native-build details](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/OPERATOR-SETUP.md) - [Configuration and spending limits](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/CONFIGURATION.md) - [Signer backends](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/SIGNING.md) - [Renewal and recovery](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/RENEWAL.md) - [Onchain discovery format and authentication](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/SPL-RECORD-LISTINGS.md) - [Tested rent, swap and retry examples](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/CLIENT-PAYMENT-CHECKS.md) - [Feature map and test coverage](https://raw.githubusercontent.com/bropump/neiro-payment-network/main/docs/FEATURE-MAP.md) - [Kora config template](https://github.com/bropump/neiro-payment-network/blob/main/examples/operator/kora.toml) - [Signer template](https://github.com/bropump/neiro-payment-network/blob/main/examples/operator/signers.toml) - [NEIRO ID](https://github.com/bropump/neiro-id) — separate naming protocol.
