  • Support for Ethereum configuration of 0 cost for gas
  • New simplified wallet address format
  • Important bug fixes and performance improvements

1.2.0

  • transfer_asset, issue_asset, create_rule, delete_rule, unlock_wallet endpoints were updated to work asynchronously
  • New get_status endpoint allows querying the status of pending transactions
  • Important bug fixes and performance improvements

1.3.0

  • Support For Samsung Nexledger Blockchain stack
  • New /health endpoint for monitoring deployment health status
  • New /wallet/get_wallet_activity endpoint (replaces /analytics/get_transactions) allows retrivel of all related wallet activity including issuances and rules updates.
  • New /analytics/get_network_activity endpoint (replaces /analytics/get_blocks) allows monitoring of all QEDIT related activity on the blockchain including proofs of asset transfer, proofs of issuance, and rules updates.
  • “wallet_label” parameter renamed to “wallet_id” across all endpoints
  • Important bug fixes and performance improvements

1.4.0

Task Listing:

  • New endpoint get_tasks
  • Lists all tasks and their current statuses

Sender ID:

  • ID is defined by Wallet public key
  • Attached to all transfers and issues, and integral part of rules
  • Verified by receiver
  • Returned in get_wallet_activity endpoint

New Auditor view enabled by two new endpoints:

  • export_auditor_access_wallet
  • import_auditor_access_wallet
  • An auditor wallet allows access to all endpoints that do not write anything to the blockchain
  • The wallet in particular does not allow transfers, issuance or rule creation
