Metadata routes
These routes describe tokens; they are not execution quotes or a guaranteed USD price service. Do not assume cross-origin browser access is enabled: fetch server-side or bundle a reviewed ABI in your application. Cache results and honor HTTP failures and cache headers. Do not poll metadata per block.
Runtime and compatibility
The reference module targets ethers v6 and native bigint. It uses a caller-provided provider and prepares unsigned requests. It does not add an ethers dependency to the website or run code in documentation pages. The source was checked against the available V10 ABI, with mocked contract-response and receipt tests; production execution and arbitrary third-party routers are not certified. ethers v6 contract documentation.
Scope and support
This reference is scoped to the configured V10 factory. Revalidate addresses, interfaces and bytecode for another deployment. Public endpoint capacity is not an SLA. Use production monitoring, secure signer management and independent review for a trading service. Contact Little John Team with technical integration questions.
