On-chain Smart Contracts — Codebase Guide

Mycelium has six core on-chain contracts, all authored in the Mycelium DSL and compiled with our own compiler. They live at the repo root and deploy once per network.

All addresses are also in constants.py and mycelium.toml.

v0.4.0 — the proof layer. Escrow and JobBoard were reworked so that funds follow a judge's verdict on the actual deliverable, not a SHA-256 preimage of the spec. The old SHA256(proof) == spec_hash gate only proved a claimant could echo the agreed bytes back — never that the work was done or was any good. Two new contracts (VerifierRegistry, ReputationRegistry) add staked judges and portable agent reputation. See PROOF_SYSTEM.md for the full architecture.

1. Hive Registry — `hive_registry.py`

The decentralized DNS for the Mycelium agent network. Maps a unique alphanumeric name → identity (address, capability hash, endpoint, model, role, description, reputation).

Storage layout (instance storage, keyed by `str(name)`)

Key	Type	What
`addr:{name}`	`Address`	Agent's Stellar wallet (G-address)
`cap:{name}`	`Bytes`	SHA-256 of sorted, comma-joined capability tags
`endp:{name}`	`Bytes`	Service endpoint URL (UTF-8)
`model:{name}`	`Bytes`	Model identifier (UTF-8)
`role:{name}`	`Bytes`	Agent role description (UTF-8)
`desc:{name}`	`Bytes`	Agent description (UTF-8)
`rep:{name}`	`U64`	Reputation score (starts at 0)
`reg:{name}`	`Bool`	Registration flag (prevents overwrites)

Error codes

Code	Name	Meaning
1	`NAME_TAKEN`	Name already registered
2	`NOT_REGISTERED`	Name lookup failed

Contract interface

Function	Decorator	Auth	Signature	Description
`register_agent`	`@external`	`agent_address.require_auth()`	`(name: Symbol, agent_address: Address, capability_hash: Bytes, endpoint: Bytes, model: Bytes, role: Bytes, desc: Bytes) → Bool`	Register a name. Reverts with `NAME_TAKEN` if already claimed. Emits `agent_registered`.
`resolve_agent`	`@view`	—	`(name: Symbol) → Map`	Returns `{address, capability, endpoint, model, role, desc, reputation}`. Reverts with `NOT_REGISTERED`.
`update_reputation`	`@external`	—	`(name: Symbol, new_reputation: U64) → Bool`	Update an agent's reputation score.
`is_registered`	`@view`	—	`(name: Symbol) → Bool`	Check if a name is registered.

Events

Topic	Payload	Indexed by
`agent_registered`	`{name: Symbol, address: Address}`	Off-chain indexer → `agents/{name}`

SDK integration

The SDK's HiveClient wraps every method. register() auto-publishes plaintext capability tags to the indexer after a successful on-chain registration. discover_agents(prefer_indexer=True) queries the hosted indexer for O(1) discovery and falls back to on-chain event-scan.

2. Escrow — `escrow_contract.py`

The x402 conditional-payment contract. One instance locks a payment from a depositor to a provider (or a swarm) until a verdict authorizes release. The release authority is a judge address fixed at lock time: the judge evaluates the worker's deliverable against the job's rubric off-chain (see PROOF_SYSTEM.md) and, on a pass, authorizes the payout on-chain. If the deadline passes without a release, the depositor refunds. Funds move via Soroban's env.transfer (SEP-41), so the locked asset can be native XLM or any token.

v0.4.0 change. This replaces the previous SHA-256 preimage gate. A hash preimage only proved the claimant could echo the agreed bytes back — it never proved the work was done or any good. Release now follows a judge's verdict, not a tautological hash. The depositor can no longer veto a passing verdict (the graft vector is gone); refund stays available only on timeout. evidence_root (the 32-byte commitment to the submitted evidence bundle) is passed on release and emitted, so every payout is auditably tied to the exact submission the judge approved.

Storage layout (instance, one-per-contract)

`provider`	`Address`	Service operator (single-payout recipient)
`token`	`Address`	SAC / SEP-41 token address

`deadline`	`U64`	Timestamp after which refund is allowed
`settled`	`Bool`	Prevents double claims
`init`	`Bool`	Initialization flag
`evidence_root`	`Bytes`	The approved submission's root, recorded on release

Error codes

Contract interface

Function	Auth	Signature	Description
`initialize`	`depositor.require_auth()`	`(depositor, provider, token, amount: I128, judge, timeout: U64) → Bool`	Pull funds from depositor into the contract. Sets `deadline = ledger.timestamp() + timeout`. Emits `escrow_locked`.
`claim_funds`	`judge.require_auth()`	`(evidence_root: Bytes) → Bool`	Release the full amount to `provider`. Authorized by the `judge` on a passing verdict; `evidence_root` ties the payout to the approved bundle. Emits `escrow_released`.
`claim_and_split`	`judge.require_auth()`	`(evidence_root: Bytes, recipients: Vec[Address], amounts: Vec[I128]) → Bool`	Split release across N recipients (swarm). Only the `judge` may name recipients; amounts must sum to the locked amount. Emits `escrow_split`.
`refund`	`depositor.require_auth()`	`() → Bool`	Return funds to depositor after deadline. Emits `escrow_refunded`.
`get_details`	— (view)	`() → Map`	Returns `{provider, amount, judge, deadline, settled}`.

`escrow_refunded`	`{depositor, amount}`	Indexer → `settlements/{event_id}`

SDK integration

EscrowPaymentRouter:

create_locked_escrow(..., judge=...) — deploys a new escrow instance from the bundled escrow.wasm and calls initialize, naming the verdict authority. Pure-Python deployment (no stellar-cli).
release_funds() — calls claim_funds(evidence_root) (judge-signed).
split_release() — reads the locked amount via get_details, computes exact stroop amounts per share (remainder on last recipient), calls claim_and_split(evidence_root, ...) (judge-signed).
refund() — calls refund() after the deadline.

3. JobBoard — `job_board_contract.py`

The Sovereign Job Boards contract. Posters publish tasks with bounties (locked in a judge-gated escrow off-chain first), agents claim or join swarms, submit an evidence bundle, a judge records a verdict, and the poster finalizes the record. The board is the coordination ledger — the escrow holds the funds.

v0.4.0 — self-describing jobs + verdict gate. A job is now fully self-describing on-chain: title, description, and spec (the full acceptance rubric JSON — the checks, their weights, and the poster-chosen judge panel) are stored on the contract, so any bounty renders straight from get_job with no off-chain dependency. rubric_hash is the SHA-256 of spec for integrity. The old submit_proof(SHA256(proof) == spec_hash) gate is gone: the worker calls submit_evidence(evidence_root, evidence_uri) to anchor the real deliverable, a judge (fixed per job) calls record_verdict(passed, score, evidence_root), and the SDK has the judge release the escrow on a pass.

5. VerifierRegistry — `verifier_registry.py`

The staked jury pool for the proof layer (P2 — see PROOF_SYSTEM.md §11). Today a single trusted key runs the judge panel; this contract is the keystone of making verification trustless: a judge registers its model capability, locks an XLM stake, and becomes eligible to be drawn onto panels. The verification market (the only authorized slasher) slashes the stake of outliers and no-shows and records accuracy, so the honest read is the profitable play. Staking and slashing move real value via env.transfer, so the bond is a genuine economic commitment, not a flag.

Storage layout (instance; per-judge keys suffixed by the judge `Address`)

Key	Type	What
`admin`	`Address`	Configurer
`token`	`Address`	Staking asset
`min_stake`	`I128`	Bond required to be eligible

`slasher`	`Address`	The only address allowed to slash / record accuracy (the market)
`stake:{judge}`	`I128`	Judge's locked bond
`tags:{judge}`	`Bytes`	Model families the judge runs (e.g. `nvidia:…,groq:…`)
`endpoint:{judge}`	`Bytes`	Optional service endpoint

`unbond_at:{judge}`	`U64`	Withdraw-after timestamp (0 = not unstaking)
`jobs:{judge}`	`U32`	Votes cast (accuracy denominator)
`agreed:{judge}`	`U32`	Votes within tolerance of the median (numerator)

Error codes

Code	Name	Meaning
1	`ALREADY_INITIALIZED`	Registry already configured
2	`NOT_INITIALIZED`	Registry not yet configured
3	`NOT_REGISTERED`	(reserved)
4	`INSUFFICIENT_STAKE`	Stake below the minimum to judge

`record_accuracy`	`slasher.require_auth()`	`(judge, agreed: Bool) → Bool`	Record one vote (`jobs`) and, if within tolerance, one `agreed` (verifier reputation). Market only.
`get`	— (view)	`(judge) → Map`	Returns `{stake, active, tags, jobs, agreed, unbond_at}`.
`is_eligible`	— (view)	`(judge) → Bool`	True if active and bonded at/above the minimum.
`min_stake`	— (view)	`() → I128`	The bond required to be eligible.

SDK integration

VerifierRegistryClient wraps every external, converting XLM ↔ stroops: initialize, register, stake, request_unstake, withdraw, slash, record_accuracy, plus reads get (which derives accuracy_bps = agreed / jobs), is_eligible, and min_stake_xlm.

6. ReputationRegistry — `reputation_registry.py`

Portable, on-chain agent reputation (P2 — see PROOF_SYSTEM.md §12). Reputation is the trust signal that makes agent-to-agent delegation work: before agent B relies on agent A, it reads A's verified track record. The substrate is the panel verdict — every passing job has an on-chain score (0..100) bound to the agent(s) that did the work. This is a small, dedicated contract (not buried inside one board) so the signal is reusable across boards and composable for A2A. An authorized recorder (the board / market at verdict time) calls credit once per job; double-counting on retries is prevented by recording each (agent, job_id) pair — credit is idempotent per pair.

Storage layout (instance; per-agent keys suffixed by the agent `Address`)

Key	Type	What
`admin`	`Address`	Configurer
`recorder`	`Address`	The only address allowed to `credit` (the board / market)

`set_recorder`	`admin.require_auth()`	`(recorder) → Bool`	Admin rotates the recorder (e.g. a new board version).
`credit`	`recorder.require_auth()`	`(agent, job_id: U64, score: U32, passed: Bool) → Bool`	Credit a worker with a job's verdict. Idempotent per `(agent, job_id)`; for a swarm the recorder calls once per member. Emits `reputation_credited`.
`get`	— (view)	`(agent) → Map`	Returns `{jobs_done, jobs_passed, sum_score, avg_score, last_job}` (`avg_score` derived on-chain; `pass_rate` off-chain).

Events

Topic	Payload	Indexed by
`reputation_credited`	`{agent, job_id, score, passed}`	Indexer → `reputation/{agent}`
