Prepare for Mainnet

Review an XL1 application before moving from Sequence to Mainnet.

Owner: XYO Layer One maintainers · Last verified: September 17, 2026

Mainnet uses real XL1 and irreversible public transactions. Complete this review before changing the configured network.

Application

• All payload schemas and size bounds are explicit.

• Application payloads are validated after every read.

• The selected network and account are visible before approval.

• Duplicate submission and uncertain-result behavior are documented.

• Finality is observed through @xyo-network/xl1-sdk, not inferred from submission.

Security

• Browser code never receives recovery phrases, private keys, or provider secrets.

• Server-side secrets use an approved secret store and rotation process.

• Logs and errors are reviewed for credential leakage.

• Dependencies are limited to reviewed public npm libraries.

Operations

• Sequence tests cover reconnects, insufficient balance, rejected transactions, and delayed finality.

• Indexers resume from durable finalized checkpoints.

• Alerts distinguish provider availability, submission, inclusion, and finality.

• Rollback and incident owners are named before launch.
