The brain and the entire fund-control policy are configured from environment variables. No code changes are needed to change a limit, and nothing the model outputs can override them, because the policy is enforced in deterministic, unit-tested code.
export OPENAI_API_KEY=sk-...
# optional overrides:
export LYRA_LLM_BASE_URL=https://api.openai.com/v1 # any OpenAI-compatible endpoint
export LYRA_LLM_MODEL=gpt-4o-mini # default model
Any OpenAI-compatible model works. Swapping the model has no effect on the safety boundary.
LYRA_POLICY_MAX_NATIVE_SUI=2.0 # hard cap: block sends over 2 SUI
LYRA_POLICY_AUTO_MAX_NATIVE_SUI=0.1 # auto-execute up to 0.1 SUI; above this requires approval
LYRA_POLICY_MAX_SLIPPAGE_BPS=100 # block swaps over 1% slippage
LYRA_POLICY_AUTONOMY=auto # auto | confirm | readonly
LYRA_POLICY_RECIPIENT_ALLOWLIST=0xabc...,0xdef... # Sui addresses (0x + 64 hex)
LYRA_POLICY_TOKEN_ALLOWLIST=0x...::usdc::USDC,... # Sui coin types
LYRA_POLICY_READONLY=1 # reject all writes
| Variable | Controls |
|---|---|
LYRA_POLICY_MAX_NATIVE_SUI | Hard cap on native SUI per action. A value above this blocks. |
LYRA_POLICY_AUTO_MAX_NATIVE_SUI | The amount the agent may move without prompting. Above it, approval is required. |
LYRA_POLICY_MAX_SLIPPAGE_BPS | Maximum allowed swap slippage, in basis points. |
LYRA_POLICY_AUTONOMY | auto (act within tier), confirm (prompt on writes), readonly (no writes). |
LYRA_POLICY_RECIPIENT_ALLOWLIST | Comma-separated recipient Sui addresses the agent may send to. |
LYRA_POLICY_TOKEN_ALLOWLIST | Comma-separated Sui coin types the agent may touch. |
LYRA_POLICY_READONLY | When set, all writes are rejected outright. |
The approval floor sits beneath the autonomy tier: a material-risk action prompts for a human even under auto / YOLO, and is denied under readonly / strict.

Gas token is SUI (9 decimals; smallest unit is MIST, 1 SUI = 1e9 MIST). Sui does not use numeric Sui chain IDs. Start on Sui testnet for exploratory work, then move to mainnet once your policy is set.
