Deployment

Program ID

TRibg8W8zmPHQqWtyAD1rEBRXEdyU13Mu6qX1Sg42tJ

• Same ID on Devnet and Mainnet. The program is not redeployed with a new ID per environment — integrations hard-code the single ID above.
• No Testnet deployment. Tributary is not deployed to Solana Testnet.

RPC endpoints

Network	Default RPC	Notes
Mainnet	https://api.mainnet-beta.solana.com	Rate-limited public endpoint; use a private RPC (Helius, Triton, QuickNode) for production.
Devnet	https://api.devnet.solana.com	Airdrop only; suitable for integration tests.
Local	http://localhost:8899	Surfpool / solana-test-validator for unit tests.

Configure via solana config set --url <rpc> or pass --url per command.

Verifying a deployment

solana program show TRibg8W8zmPHQqWtyAD1rEBRXEdyU13Mu6qX1Sg42tJ

Output should show:

• Program owner: the BPF Upgradeable Loader
• ProgramData address and the upgrade authority
• Last deploy / slot

On Mainnet, cross-check the upgrade authority against the published multi-sig / authority in the repository README before trusting a deployment.

Verifying program bytecode

solana program dump TRibg8W8zmPHQqWtyAD1rEBRXEdyU13Mu6qX1Sg42tJ tributary.so --url <rpc>
# compare against the locally built artifact
sha256sum tributary.so target/deploy/tributary.so

Local development

# Surfpool — the preferred local validator for Tributary tests
surfpool start --legacy-anchor-compatibility --no-tui

# or stock test-validator (does not emulate mainnet state)
solana-test-validator --bpf-program TRibg8W8zmPHQqWtyAD1rEBRXEdyU13Mu6qX1Sg42tJ target/deploy/tributary.so

Integration tests (tests/ jest suite, tests/topup-balance*.test.ts) are designed against Surfpool — see the repo's AGENTS.md for the exact invocation.

Network feature notes

• Token-2022 / extensions: rejected with UnsupportedTokenExtension. Use plain SPL token mints for user funds.
• Compute budget: composable executions with a forward + validation path can exceed the default 200k CU budget. Add a ComputeBudgetProgram.setComputeUnitLimit instruction (400k–1M) in front of execute_composable.
• Priority fees: recommended on Mainnet for execute_* to avoid landing in low-fee queues during congestion.

Upgrades

Program upgrades are gated by the upgrade authority (see solana program show). Tributary does not use a separate upgrade authority multisig in devnet — on Mainnet the upgrade authority should be a Squads multisig (verify before trusting). State migrations are not supported; the program is forward-only and account layouts are padded to absorb new fields without redeployment.

See Changelog for the history of upgrades.
