Ledger release v2.1.0

Release date: March 8, 2023

Multitenancy

We’ve implemented support for multitenancy. This means that now Ledger is able to support multiple clients/tenants (ledgers) on one Ledger instance. Active ledger will be resolved by looking at a subdomain. For example: https://ledger.ldg-stg.one will resolve ledger with handle ledger and https://minka.ldg-stg.one will resolve ledger with handle minka.

CLI is update to support new command for selecting a ledger:

$ minka ledger select
? Ledger: sandbox

For existing clients/instances there will be no change, unless explicitly communicated.

Improved bridge support

We have aligned Bank integration tutorial with all the latest changes from this version with focus on API schema changes.

Other important changes

• API schema changes to improve API consistency
  • changed signer schema to format
  • changed meta.signatures to meta.proofs
  • changed proofs (formerly signatures) schema to method
• changed bridge payload schemas
  • to be future-proof, we have changed source, target and symbol parameters from strings to objects to enable us to include additional metadata in those parameters
• updated 2-phase commit payload
  • commit Actions are sent to POST /credits/:handle/commit and POST /debits/:handle/commit
  • abort Actions are sent to POST /credits/:handle/abort and POST /debits/:handle/abort
• implemented API versioning: changed base URL to v2
  • all API call will now have additional v2 part. For example, instead of calling /signers/{handle}/changes/{change} ****you should call /v2/signers/{handle}/changes/{change}
• supported proofs verification in SDK
• updated error codes. See more here: Error reference
• updated documentation
  • updated access object example in API reference documentation
  • updated API spec for intent processing
  • updated existing docs with multitenancy support
