Resolving Common Deployment Errors on the Redbelly Network

The guide, compiled in August 2026 against the portal's current documentation, works backward from observed failure states to their root cause — not the other way around.

The deprecated chain ID

DevNet (chain ID 152) is formally retired. Any legacy config carrying it forward is invalid. All contract testing now happens on Testnet (chain ID 153, returning 0x99 in hex). Mainnet lives on chain ID 151 (0x97).

Mixing these is the most common state of failure. Mainnet and Testnet are separate, non-interoperable environments. RBNT on one has no relationship to RBNT on the other. Wallets and dApp providers can land on different networks without either side complaining.

Pin the network parameters once. Import them from a shared config module. Duplicate Hardhat configs, frontend providers, and .env files are an invariant violation waiting to happen.

RPC failures are not what they look like

Requests to governors.testnet.redbelly.network stalling with a generic Failed to fetch does not mean Redbelly is down. The public RPC is opaque. The first move is to rule out local configuration drift before assuming an outage.

Do not retry the same broken URL in a loop. If chain ID checks fail, the fix is identifying what the stack is actually pointed at — not hammering the endpoint.

Write access is gated, not granted

Read calls work. eth_chainId returns correctly. The wallet shows a balance. Then any transaction that writes to the chain reverts with a generic execution error or an unhelpful internal failure.

This is the precondition: Redbelly requires a claimed Network Access Credential before write permission is granted at the account level. This is not optional KYC bolted onto a standard EVM chain. It is a control baked into the network's access model.

Wallet onboarding alone is insufficient. The credential state must be resolved before any deployment or state mutation.

Pre-flight checks for a fresh setup

• Chain ID matches 153 (Testnet) or 151 (Mainnet). Confirm with eth_chainId.
• RPC endpoint URL is defined once and consumed everywhere.
• Network Access Credential is claimed and confirmed before the first write.
• No DevNet (152) config remnants in any environment file or CI cache.

The guide's core thesis is correct: most "Redbelly doesn't work" tickets trace back to one of these four states being wrong, stale, or mismatched between two parts of the stack. Audit them before deploying anything.
