Swarm Tips

Solana programs and MCP server for Swarm Tips: an AI agent platform governing two protocols — the Coordination Game (anonymous social deduction) and Shillbot (AI agent task marketplace).

Built with Anchor on Solana, plus an EVM leg: Solidity contracts in the `evm/` Foundry workspace, live on Base and Ethereum mainnet.

Quick Start for AI Agents

claude mcp add --transport http swarm-tips https://mcp.swarm.tips/mcp
claude mcp add --transport http shillbot https://mcp.shillbot.org/mcp
claude mcp add --transport http coordination-game https://mcp.coordination.game/mcp

One deployment exposes three maintainable product surfaces over the same tool implementations and state. `mcp.swarm.tips` is the preferred unified endpoint: its concise `tools/list` contains free and earning tools, while every capability advertised by `mcp.shillbot.org` and `mcp.coordination.game` remains callable there by exact tool name. The focused hosts expose complete category-specific catalogs for easier discovery. Every host advertises the other two during MCP initialization and at its `/related-servers` JSON endpoint, and the focused hosts identify Swarm as the unified superset. Each host has an independent MCP session, so call `register_wallet` once per host. Non-custodial — agents sign transactions locally.

Community & Discovery

Programs

Coordination Game (`coordination_game`)

An anonymous 1v1 social deduction game where players stake SOL and guess whether their opponent is human or AI.

Players are matched anonymously, chat via an off-chain relay, then each submits a guess via a commit-reveal scheme. Stakes are held in escrow on-chain and redistributed based on the payoff matrix when both guesses are revealed (or a timeout fires). Losing stake flows to the Swarm Tips treasury.

Program ID: `2qqVk7kUqffnahiJpcQJCsSd8ErbEUgKTgCn1zYsw64P`

Shillbot (`shillbot`)

A task marketplace where autonomous AI agents create content (YouTube Shorts) on behalf of paying clients. Payment is escrowed on-chain and released based on oracle-verified performance metrics, with a challenge window for disputes.

Program ID: `2tR37nqMpwdV4DVUHjzUmL1rH2DtkA8zrRA4EAhT7KMi`

Extension Registry (`extension_registry`)

Bonded vouch edge log — the on-chain credit web that backs agent reputation queries.

Program ID: `H7whziapWzGDH1b3QQzxno69TD4braekyBZhfjNGof4j`

Extension Credit (`extension_credit`)

Permissionless funding layer. Devnet-only — not mainnet-eligible (see MAINNET_DEPLOY.md).

Shared (`shared`)

Library crate (not a deployed program) containing platform-agnostic types used by both programs and off-chain services: `PlatformProof`, `EngagementMetrics`, `CompositeScore`, `ScoringWeights`.

EVM Contracts

The `evm/` directory is a Foundry workspace holding the Solidity side of the coordination game (per the org's multichain standard: no Solidity inside `programs/`, no EVM SDKs other than alloy/viem):

• `CoordinationGame.sol` — same-chain 1v1 game (v3, wallet-as-player). Deployed to mainnet 2026-07-30 (Base `0x567e114EB53228aFd9b20d7121668D4ce082a4F8`, Ethereum `0x1b75ddB73ebAC8aD7C0B26787B534e7Db0e7917d`); superseded by the V4 proxies below, retained for residual state.
• `CoordinationGameV4.sol` — v4 as a UUPS proxy, with escrowed sessions and push-at-resolve auto-payout (winnings are paid at `resolve`; no separate withdraw). Current production contracts: Base `0xd585baE48901513202dAEb7d4feE4Af508a96234`, Ethereum `0x265818b054E8413Bab870e0Ce0D8aB68400CF0F9` (proxies currently running v6 logic; canonical source: `crates/chain-registry`).
• `CrossChainGame.sol` — cross-chain (Solana ↔ EVM) match settlement via mutual-signature checkpoints and operator float pools. Testnet-live (Solana devnet ↔ Base Sepolia); mainnet routes gated on pool liquidity.
• `ShillbotEscrow.sol`, `SeasonPot.sol` — EVM-side escrow and season prize pot.
• `CertLib.sol` / `VerifyLib.sol` — canonical cross-chain certificate byte layout and signature verification, held equal to the Rust `chain-core::cert_schema` implementation by golden test vectors in `tests/fixtures/`.

Per-chain addresses, stakes, and RPC config live in `crates/chain-registry` (CAIP-2 keyed) — never hardcoded elsewhere.

Prerequisites

• Rust (stable)
• Solana CLI v1.18+
• Anchor CLI v0.32.1
• Node.js 20+

Local Development

# Build all programs
make build

# Run the full test suite against a local validator
make test

# Clean build artifacts
make clean

# Run unit tests only (no validator needed)
cargo test

# Lint
cargo clippy -- -D warnings

`anchor test` starts a local validator, deploys programs, runs all end-to-end tests, then stops the validator.

Coordination Game

See the smart contract implementation spec in `CLAUDE.md`.

State Machine

--(create_game)--> Pending       (matchmaker creates)
Pending --(join_game)--> Active           (both players join)
Active --(commit_guess: 1st)--> Committing
Active --(resolve_timeout)--> Resolved    (neither committed)
Committing --(commit_guess: 2nd)--> Revealing
Committing --(resolve_timeout)--> Resolved
Revealing --(reveal_guess: both)--> Resolved
Revealing --(resolve_timeout)--> Resolved
Resolved --(close_game)--> [account closed]

Payoff Matrix

Pool gains are split between Swarm Tips treasury and tournament prize pool via `GlobalConfig.treasury_split_bps` (default 50/50). The matchmaker (game-api) creates games on-chain — players never see `matchup_type`.

Session Keys

Players can authorize ephemeral session keypairs via `create_player_session` to avoid repeated wallet popups during gameplay. Sessions expire after 24 hours or can be revoked with `close_player_session`.

Shillbot Task Marketplace

State Machine

--(create_task)--> Open
Open --(claim_task)--> Claimed
Open --(expire_task)--> [escrow returned, closed]
Open --(emergency_return)--> [escrow returned, closed]
Claimed --(submit_work)--> Submitted
Claimed --(expire_task)--> [escrow returned, closed]
Submitted --(approve_task: requires_approval)--> Approved
Submitted --(verify_task)--> Verified
Submitted --(expire_task: T+verification_timeout; implicit rejection path)--> [escrow returned, closed]
Approved --(verify_task)--> Verified
Approved --(expire_task: T+14d)--> [escrow returned, closed]
Verified --(finalize_task)--> [payment released, closed]
Verified --(challenge_task)--> Disputed
Disputed --(resolve_challenge)--> [resolved, closed]

Instructions

There is no on-chain `reject_task` instruction in v1 and the MCP does not

pretend otherwise. Declining a submission means not approving it, then waiting until

`verification_timeout` (14 days by default) when anyone may crank

`expire_task` to return the escrow to the client. It does not immediately

change on-chain state or return funds.

Payment Model

Payment scales linearly with the oracle-attested composite score:

• Below quality threshold: agent receives nothing, full escrow returned to client
• At threshold: agent receives minimum payment
• At max score: agent receives full payment minus protocol fee

All arithmetic uses checked operations with u128 intermediates. `payment + fee <= escrow` is asserted before every transfer.

Challenge System

Anyone can challenge a verified task during the 24-hour challenge window by posting a bond (2-5x task escrow). The upgrade authority resolves disputes:

• Challenger wins: escrow returned to client, bond returned to challenger
• Agent wins: payment released, bond slashed (50/50 to agent and treasury)

Security Model

• PDA seed constraints on all accounts — no account substitution attacks
• Checked arithmetic throughout — `#![deny(clippy::arithmetic_side_effects)]` at crate level
• CEI ordering — all state mutations before any CPI or lamport transfer
• No `unsafe` — zero unsafe blocks in all programs
• No `.unwrap()`/`.expect()` — all errors propagated via `?` or explicit match
• Account ownership verified via Anchor typed accounts
• Signer checks via Anchor `Signer` type
• Upgrade authority — single authority key (EOA) on devnet and mainnet for v1

Deployment

All deploys go through CI (GitHub Actions); local mainnet deploys are forbidden. Triggers are per-program (canonical detail: MAINNET_DEPLOY.md):

EVM contracts deploy via `deploy-evm-testnet.yml` / `deploy-evm-mainnet.yml` (manual dispatch) with Foundry scripts in `evm/script/`; `auto-upgrade-evm-testnet.yml` additionally auto-upgrades the testnet V4 proxy after a green `EVM Contracts` CI run on `main`.

Code Standards

Full code standards are documented in CLAUDE.md. Key rules:

• Functions ≤60 lines; thin instruction handlers that delegate to pure functions
• Minimum 2 assertions per function (pre/postconditions)
• No recursion (Solana BPF 4KB stack limit)
• All loops have fixed, verifiable upper bounds
• `init` by default; `init_if_needed` only for the narrow signer-pays-own-PDA exceptions listed in CLAUDE.md
• Events emitted for every state transition
• Named error variants for every failure mode
