Indra v7.3.11

New Features

• #1405 - Improved collateral management (explanation below)

Improved Collateral Management

Node

• Admin endpoints to add and view rebalance profiles per channel/asset combo. Example requests:

# Add Rebalance Profile
POST http://localhost:3000/api/admin/rebalance-profile
Content-Type: application/json
x-auth-token: cxt1234

{
  "multisigAddress": "0x93a8eAFC6436F3e238d962Cb429893ec22875705",
  "rebalanceProfile": {
    "assetId": "0x4E72770760c011647D4873f60A3CF6cDeA896CD8",
    "collateralizeThreshold": "5",
    "target": "15",
    "reclaimThreshold": "0"
  }
}

###
# Get Rebalance Profile

GET http://localhost:3000/api/admin/rebalance-profile/0x93a8eAFC6436F3e238d962Cb429893ec22875705/0x0000000000000000000000000000000000000000
Content-Type: application/json
x-auth-token: cxt1234

• New environment variables exposed for setting default collateralization limits. Set using stringified JSON.
  • INDRA_DEFAULT_REBALANCE_PROFILE_ETH
  • INDRA_DEFAULT_REBALANCE_PROFILE_TOKEN - Currently applies across all tokens

Example:

export INDRA_DEFAULT_REBALANCE_PROFILE_TOKEN='{"assetId":"0x4E72770760c011647D4873f60A3CF6cDeA896CD8","collateralizeThreshold":"10000000000000000","target":"50000000000000000","reclaimThreshold":"200000000000000000"}'

Client

• Optional amount field added to requestCollateral method. amount can be larger than target but must be less than reclaimThreshold.

Indra 7.3.6 | Client 7.3.6

• Includes fix to save transaction request, even if it immediately fails
• USDT compliant (different from ERC20 compliant)

indra-7.3.5 | client-7.3.5

Indra v7.3.1

Bugfixes

• #1380 - Fix withdrawal contracts to support non-conforming ERC20 contracts using Uniswap's safeTransfer.
• #1379 - Transfer behavior is more predictable and will not continue on node-side if collateralization takes too long, which already triggered a client-side timeout.

Indra v7.3.0

indra-7.3.0

Deploy indra-7.3.0

Indra v7.2.0 | Client v7.2.0

New features:

• Linked transfers that require the recipient to be online: channel.conditionalTransfer({ conditionType: ConditionalTransferTypes.OnlineTransfer })
• Support for all side-chains that spacefold supports + improved ETC support.

Indra v7.1.1

API Changes

• #1359 - Client API methods deposit and requestCollateral now return without waiting for the completion of an onchain tx. The methods return a function completed() as part of the response to allow waiting for the full process including the onchain tx and offchain protocol (inspired by Ethers' await tx.wait() API).

An example deposit call:

import { BigNumber, constants } from "ethers";
const response = await client.deposit({ amount: BigNumber.from(10), assetId: constants.AddressZero });
// deposit method returns quickly

await response.completed();
// tx complete, channel balance updated

New Features

• #1073 - Added groundwork for supporting Grafana and Prometheus to provide a node operator dashboard. More to come.

Bugfixes

• #1340 - Fix cases where onchain tx was taking too long when the receiver needed to be collateralized.
• #1153 - Add more reliable onchain transaction tracking to cf-core.
• #1331 - Fix issue where mainnet was getting spammed by error logs from SwapRateService.
• #1347 - More reliable process around withdrawing to enable node to send the client a tx hash immediately.
• #1327 - Ops bug.
• #1332 - Reenable config endpoint with old API (without chainId specification).
• #1330 - Fix pruneExpiredApps task
• #1332 - Hard limit on number of apps allowed in a channel.
• #1323 - Allow locking on just the appIdentityHash rather than full channel locks.
• #1298 - Add version number to protocol, follows semantic versioning.
• #1087 - Delete commitments on uninstall.
• #1310 - Cooperative cancel for receiver.
• #1317 - Retry failed txes.

Breaking Changes

• Node env var INDRA_ETH_PROVIDER has been changed to INDRA_CHAIN_PROVIDERS to support multi-chain configuration. Example usage:

# .env
export INDRA_CHAIN_PROVIDERS="{\"1337\":\"http://172.17.0.1:8545\",\"1338\":\"http://172.17.0.1:8546\"}"

• Node env vars INDRA_ETH_MNEMONIC, INDRA_ETH_MNEMONIC_FILE, and INDRA_ETH_CONTRACT_ADDRESSES are changed to be chain-agnostic: INDRA_MNEMONIC_FILE, INDRA_MNEMONIC, and INDRA_CONTRACT_ADDRESSES.
• Supported node env vars are listed below. Any env vars that are not listed are no longer supported.
