Configuration

Environment variables and defaults.

Database and wallet vault

Variable	Default / alias	Meaning
`SLRD_DB_PATH`	`~/.solard/solard.sqlite`	Shared SDK/CLI SQLite database. `SOLARD_DB_PATH` is accepted as an alias.
`SLRD_MASTER_KEY`	unset	Explicit wallet-encryption/signing key for CI or automation. The CLI otherwise prompts for an ephemeral wallet password on signing commands and does not persist that password.

RPC and indexed history

Variable	Default	Meaning
`RPC_ENDPOINT`	—	Primary Solana JSON-RPC endpoint for chain operations.
`HELIUS_RPC_URL`	—	Helius RPC endpoint used by ordinary Helius-RPC execution paths and as an available chain endpoint.
`HELIUS_API_KEY`	—	Helius API key used by integrations that construct Helius endpoints from a key.
`SLRD_RPC_MAX_RPS`	`5`	Global maximum Solard JSON-RPC request rate. Increase only when the provider permits it.
`SLRD_RPC_NETWORK_RETRIES`	`4`	Retries for fetch-level failures such as connection resets or socket closure.
`SOLSCAN_API_KEY`	unset	Optional indexed provider for authoritative historical transfer reconstruction.
`SLRD_JUPITER_MAX_RPS`	keyless 0.5 req/s; keyed path defaults to 1 req/s	Maximum request rate for Jupiter fallback/quote traffic.
`SOLARD_EXTERNAL_HTTP_TIMEOUT_MS`	`10000` in the example environment	Timeout used by optional external HTTP intelligence/data integrations.

Guarded live-trading switch

dotenv

SOLARD_ENABLE_LIVE_TRADES=1
# Legacy aliases accepted by parts of the runtime:
# SOLWAL_ENABLE_LIVE_TRADES=1
# SLRD_ENABLE_LIVE_TRADES=1

Required by guarded flows such as Meteora and Raydium. It is not a universal gate: buy, sell, and transfer use their own execution semantics.

Sender lanes

dotenv

HELIUS_SENDER_URL=...
HELIUS_TIP_ACCOUNT=...
HELIUS_TIP_LAMPORTS=...
HELIUS_PRIORITY_MICRO_LAMPORTS=...
JITO_BLOCK_ENGINE_URL=https://mainnet.block-engine.jito.wtf

Sender ids include rpc, helius, and jito. Configure only the lane you use.

Web console API

dotenv

SOLARD_WEB_TOKEN=your-local-api-token
# Legacy alias:
# SOLWAL_WEB_TOKEN=your-local-api-token
# Explicitly disable token auth only when intended:
# SOLARD_ALLOW_OPEN_WEB=1

The web console API expects bearer-token authentication unless open-web mode is explicitly enabled.

Pump lifecycle

dotenv

SOLARD_PUMP_WS_CONNECTIONS=5
SOLARD_PUMP_SUBSCRIPTIONS_PER_CONNECTION=1000
SOLARD_PUMP_MAX_TRACKED_TOKENS=5000
SOLARD_PUMP_LIFECYCLE_REFRESH_MS=2000
SOLARD_PUMP_ACTIVE_WINDOW_MS=3600000
SOLARD_PUMP_CURVE_POLL_MS=5000
SOLARD_PUMP_CURVE_REPAIR_POLL_MS=60000
SOLARD_PUMP_REQUIRE_INTEREST_SIGNAL=false
SOLARD_PUMP_INTEREST_WINDOW_MS=1800000
SOLARD_PUMP_MIN_INTEREST_SCORE=0

Controls Pump websocket fan-out, token caps, refresh/polling, active windows, and optional interest filtering.

PumpSwap lifecycle

dotenv

SOLARD_PUMPSWAP_WS_CONNECTIONS=5
SOLARD_PUMPSWAP_SUBSCRIPTIONS_PER_CONNECTION=1000
SOLARD_PUMPSWAP_MAX_TRACKED_TOKENS=5000
SOLARD_PUMPSWAP_LIFECYCLE_REFRESH_MS=2000
SOLARD_PUMPSWAP_ACTIVE_WINDOW_MS=86400000
SOLARD_PUMPSWAP_REPAIR_POLL_MS=60000
SOLARD_PUMPSWAP_HISTORY_MS=0

Meteora DLMM

dotenv

METEORA_DLMM_CLUSTER=mainnet-beta
METEORA_DLMM_DATA_API_URL=https://dlmm.datapi.meteora.ag
METEORA_POOL_DISCOVERY_API_URL=https://pool-discovery-api.datapi.meteora.ag

These read endpoints can be overridden for proxied or self-hosted deployments. Meteora write methods additionally require explicit live intent and the guarded live-trading switch documented above.

Metadata upload

Variable	Default	Meaning
`SLRD_METADATA_UPLOADER`	`pump-frontend`	Select the default metadata uploader used by CLI metadata/launch flows.
`PUMP_IPFS_ENDPOINT`	`https://pump.fun/api/ipfs`	Browser-facing Pump metadata upload endpoint.
`PINATA_JWT`	unset	Required when explicitly using the Pinata provider or Pinata fallback.
`IPFS_PUBLIC_GATEWAY`	`https://ipfs.io/ipfs`	Public gateway used for Pinata-returned metadata URLs.

Launch transport policy

SLRD_LAUNCH_* variables define resend and timeout policy shared by launch execution. Helius launch paths also use the tip/priority variables above. These are transport/runtime settings rather than token metadata.

Optional GMGN intelligence

dotenv

GMGN_API_KEY=...
GMGN_API_URL=https://openapi.gmgn.ai
SOLARD_EXTERNAL_HTTP_TIMEOUT_MS=10000

The GMGN integration in this codebase is read-only for token/security/holder/trader/kline/trending/signal/gas data. Signed GMGN swap or order execution is intentionally not supported.
