Greptile Summary

This PR syncs documentation with recent OpenAPI schema changes by adding Ethereum L1 (USDC) wallet support and three new fiat currencies (AED, BWP, XAF) to the Grid Visualizer, extending the external accounts MDX snippet with a new Ethereum tab, and fixing an invalid businessType: FINTECH example across the OpenAPI specs.

All changes are additive and strictly follow existing conventions:

• Grid Visualizer — ETHEREUM_WALLET, AED_ACCOUNT, BWP_ACCOUNT, and XAF_ACCOUNT specs are correctly structured; crypto wallets have no paymentRails and beneficiaryRequired: false, matching the existing SPARK_WALLET/BASE_WALLET/POLYGON_WALLET pattern.
• external-accounts.mdx — The "Cryptocurrency" tab is renamed to "Bitcoin" (more accurate) and a new "Ethereum" tab is added in the same format as all other tabs, with a valid 42-character EVM address example.
• OpenAPI — The FINTECH → FINANCE_AND_INSURANCE fix is correctly made in the source file (openapi/paths/customers/customers.yaml) and the generated bundles (openapi.yaml, mintlify/openapi.yaml) are updated consistently, indicating make build was run as required by the repo's CLAUDE.md guidelines.

No issues found — the PR is clean and safe to merge.

Confidence Score: 5/5

• This PR is safe to merge — all changes are additive documentation updates that follow existing patterns with no logic errors or breaking changes.
• All seven changed files contain straightforward, pattern-consistent additions. The OpenAPI fix corrects an invalid enum value, the new account types mirror existing structure, and the new MDX tab follows the established format. Generated bundle files (openapi.yaml, mintlify/openapi.yaml) are correctly updated alongside the source change, indicating the build step was run.
• No files require special attention.

Important Files Changed

Filename	Overview
components/grid-visualizer/src/data/account-types.ts	Adds ETHEREUM_WALLET, AED_ACCOUNT, BWP_ACCOUNT, and XAF_ACCOUNT specs; follows existing patterns correctly with no paymentRails for crypto wallets and beneficiaryRequired: false only for ETHEREUM_WALLET
components/grid-visualizer/src/data/crypto.ts	Adds ETHEREUM_WALLET entry to the USDC crypto asset, consistent with existing Solana/Polygon/Base wallet entries
components/grid-visualizer/src/data/currencies.ts	Adds AED, BWP, and XAF currency entries; AED uses Bank Transfer correctly, BWP and XAF use Mobile Money; XAF countryCode is 'cm' (Cameroon) which is appropriate as a representative country for the multi-country CFA franc
mintlify/snippets/external-accounts.mdx	Renames "Cryptocurrency" tab to "Bitcoin" and adds a new "Ethereum" tab with an L1 USDC cURL example; follows existing tab structure and formatting conventions
openapi/paths/customers/customers.yaml	Fixes invalid businessType example from FINTECH to FINANCE_AND_INSURANCE in the source OpenAPI spec
openapi.yaml	Generated bundle file updated by make build; same FINTECH → FINANCE_AND_INSURANCE fix propagated from source
mintlify/openapi.yaml	Generated Mintlify bundle updated by make build; same FINTECH → FINANCE_AND_INSURANCE fix propagated from source
