Excellent list! Regarding point 8, we'll need to map out in what detail the REST endpoints are being used by the wallet and explorers. |

Sides notes: the integration documentation has not caught up with it yet. Configuring the keeper Action Item: Investigate the IBC query requirements for the Upgrade state and whether to undertake similar state work as with the staking state history availability. |
Added todo to merge revamped |
I can help with this. In general I don't do fresh code on chains, but i have gotten really good at upgrades and the like. one thing stay away from 0.44.1 |
@faddat thanks for the heads up. Specific issue? wait for v0.44.2? |
@faddat : That sounds good! You're very welcome to take a look at the on-going upgrade work on https://github.com/e-money/em-ledger/tree/v44. Please let us know if you have any suggestions or things that you want to contribute. PRs are very welcome. |
Tested the IBC test setup located in |
Seems there are a couple of gas estimation related issues in Hermes i.e., fixed in v0.7.3 informalsystems/hermes#1354 and it's unclear whether it requires configuration adjustment as discussed in the issue |
Hi, another thing -- probably best now to jump straight to v0.45.0 because it's got some performance improvements, and is state-breaking anyhow :). |
SDK API breaking changes
Impact
Build breaks and business impact needs to be assessed i.e. whether updated API is a 1-1 replacement.
Action Item
These API items need to be consulted as we migrate the codebase. v44 Api Changes
State Upgrade Details
Impact
Banking and evidence migrate to v44 state format.
Action Item
. Write the in-store migration plan and plan the chain upgrade along.
. Test a smooth IBC upgrade.
e-Money v42 multisig fix.
Impact
Needs to be migrated to v44.
Action Item
Check whether Henrik's fix has been backported to v44 otherwise, fork v44 and migrate fix and check against new ADR-028 addresses. See below.
ADR-028 Addresses i.e., secp256r1 or 32 byte addresses. doc updates
Impact
This is extending the previous Address scheme with new longer address types that would need to be integrated/tested with emd, wallet, test, and live keystores. Not clear on the status of hardware devices support.
Action
Adding a comprehensive testing suite and testing support across the board.
Upgrade modules to support in-place store migrations In store migration
Impact
Module code changes.
Action Item
None immediately unless the new functionality is desired
IBC has moved to a new repo.
Impact
The build breaks.
Action Items
Migrate existing IBC imports to the new IBC repo dependency. Check against other issues.
New proto / module folder layout changes
Impact
New streamlined module folder structure.
Action Items
The existing folder layout appears upward compatible, but we may have to compile against a revamped third_party proto folder.
Removal of legacy Rest endpoints.
Impact:
Likely none because we are using the gRPC gateway Rest Api already and had removed the legacy endpoints.
Action Item:
Check the wallet endpoints against this table.
New rest endpoints
