Consistent domain models
Accounts, instruments, quotes, balances and positions are represented through versioned schemas rather than provider-specific shortcuts.
Developer preview · read-only Demo scope
Trading access, made portable.
FXXT is an open-source developer toolkit for connecting user-authorized trading accounts through one consistent contract—with explicit capabilities, verifiable limits and evidence-bound results.

The standard
One contract. Clear evidence.
Providers expose different protocols, account models and constraints. FXXT expresses those differences instead of hiding them, so developers can build tools that remain explicit about what is supported, tested and unknown.
Capabilities over assumptions
Native, emulated, unsupported and unknown behaviors are disclosed at provider and account scope before a tool relies on them.
Results bound to scope
Compatibility statements are tied to a legal entity, region, server, account type, adapter version and reproducible test evidence.
Current scope
Deliberately narrow today.
FXXT is in a controlled developer-preview phase. Its offline contracts and safety gates have been tested locally. External Demo integrations remain subject to platform approval, account authorization and evidence-based validation.
Permitted in this phase
- Developer-owned Demo accounts only
- Read-only account information and statistics
- Local credential protection and secret-redacted logs
- Contract, recovery and reconciliation testing
Not enabled
- Order placement, modification or cancellation
- Live accounts, real funds or production traffic
- Credential collection by a hosted FXXT service
- Broker certification or provider endorsement claims
Trust model
Useful without taking control.
The project is designed around user ownership, least privilege and local-first secret handling. A provider connection is never treated as proof of compatibility by itself.
User-controlled authorization
The account owner grants and can revoke platform access. FXXT does not ask users to send credentials through chat, email or public forms.
Local-first secrets
During the developer preview, credentials remain on the developer's Windows device and are protected using the operating system's user-scoped encryption.
Fail-closed behavior
Unknown permissions, mismatched scopes, unexplained data gaps and reconciliation failures block progress rather than silently lowering safeguards.
No paid ranking
The intended public standard separates technical evidence from commercial relationships. Payment must not change compatibility or certification results.
