Independent, open-source tools for the DigiByte ecosystem — with a focus on the emerging agent economy: letting AI agents pay, prove identity, and read on-chain data on a decentralized rail.
Not affiliated with the DigiByte Foundation or core development team. These are independent community projects. Anything marked TESTNET is experimental and must never be pointed at mainnet or real funds.
The agent economy is standardizing on pay-per-call payments (x402, AP2) — but almost all of it settles in USDC on Base: an issuer that can freeze funds, on an L2 with a single sequencer. DigiByte has the decentralized rail (PoW L1, 15s blocks, sub-cent fees) and now a collateral-backed stablecoin in DigiDollar. What's missing is the tooling.
DGB secures it. DigiDollar spends it.
| Project | What it does | Status |
|---|---|---|
| dgb-digidollar-mcp | MCP server: an AI agent pays for a service in DigiDollar via the x402 pay-and-retry flow. Spend caps enforced outside the model — allowance, not custody. | 🟢 Live — real DD payments on testnet26 |
| dgb-x402 | Drop-in library so any service can emit 402 Payment Required invoices and accept DigiDollar. |
🟢 Live — full loop proven |
| dgb-x402-gateway | A public endpoint that charges for itself. Hit it, get a 402, pay $1 in DigiDollar, get live DigiByte network data back. A working demo you can call right now. |
🟢 Live — 154.12.247.176:8402 |
| dgb-chain-mcp | Let any AI agent query DigiByte directly — supply, DigiDollar stats, oracle status, price, addresses, transactions. Read-only, mainnet-safe. | 🟢 Live — on npm |
| dgb-digiid-mcp | Agent identity via Digi-ID — an agent proves who it is by signing a challenge, no passwords. | 🟢 Live — forgery-tested |
| dgb-testnet-faucet | Free testnet DGB so anyone can build and test without asking around in chat. | 🟢 Live — 154.12.247.176:8080 |
| dgb-attest-mcp | On-chain attestation — hash content onto DigiByte for permanent, timestamped, tamper-evident proof of existence. Prove what + when; pair with Digi-ID for who. | 🟢 Live — tamper-tested |
| dgb-tollgate | DigiDollar paywall for MCP servers + an autonomous paying client. An agent hits a 402, pays DigiDollar within spend caps, and gets the tool — no human in the loop. | 🟢 Live — proven on testnet |
| dgb-digidollar-codec | Read DigiDollar without a wallet: DD/TD ↔ taproot address codec + OP_RETURN record parser, from live chain data. The missing layer for explorers, processors, and facilitators. | 🟢 Live — 11 tests, real on-chain vectors |
| oracle-ops | Alerts an operator when their own oracle goes stale, stops signing, or falls behind — plus the operator's runbook (reboot recovery, learned live on slot 29). Not a dashboard — digibyte.io already has an excellent one. | 🟢 Live — running on a mainnet slot |
An AI agent paid $2.50 and $1.25 in DigiDollar to a merchant wallet on testnet26 —
confirmed on-chain — while the policy layer blocked a payment over the operator's cap
and refused to send DigiDollar to a bare DGB address. DigiDollar and DGB cannot be
confused: DD has its own address type (DD/TD/RD) and its own UTXO set.
Everything here is testnet-first and built in the open. Issues and PRs welcome — especially on DigiDollar transaction internals, where the ecosystem's knowledge is thinly spread.
