Raiden Light Client Typescript/Javascript SDK

# Changelog

## [Unreleased]

## [3.1.1] - 2022-07-28
### Fixed
- [#3161] Update dependencies and merge fixes from `v2`

[#3161]: https://github.com/raiden-network/light-client/pull/3161

## [2.3.0] - 2022-07-27
- [#3160] Backport v3.1.0 improvements to `v2` series (supporting [raiden-contracts v0.40 Coruscant](https://github.com/raiden-network/raiden-contracts/releases/tag/v0.40.0) and Ethereum Mainnet)

[#3160]: https://github.com/raiden-network/light-client/pull/3160

## [3.1.0] - 2022-06-30
### Fixed
- [#3118] Dynamically set `config.revealTimeout` to half of `tokenNetworkRegistryContract.settleTimeout`, if it'd be smaller than default of 600s

### Changed
- [#3122] `Raiden.dumpDatabase` now returns an `AsyncIterable` of database rows objects, which allow to stream even big state dumps without having to accumulate everything in memory; also, it doesn't require stopping SDK to dump state anymore

### Added
- [#3123] `Raiden.getTransfers` method, an easier way to get, filter and paginate over past transfers.

[#3118]: https://github.com/raiden-network/light-client/pull/3118
[#3122]: https://github.com/raiden-network/light-client/issues/3122
[#3123]: https://github.com/raiden-network/light-client/issues/3123

## [3.0.0] - 2022-05-02
### Fixed
- [#3106] Fix bug where `Raiden.transferOnchainTokens` with `subkey=true` could be ignored and main account used instead

### Changed
- [#2916] **BREAKING** Switched timeouts to use timestamps (seconds) instead of blocks; previous Raiden stable releases and contracts used block numbers to count the passage of time (e.g. transfers, withdraws and channel settlement timeouts); the new refactored contracts use timestamps (in seconds) instead, which is more predictable on networks with random or on-demand block generation cadence, like rollups; while this change is motivated by the Arbitrum compatiblity effort, it's not restricted to rollups, and may eventually also be deployed to other networks
- [#2976] **BREAKING** Switched to `arbitrum` branch of [raiden-contracts](https://github.com/raiden-network/raiden-contracts/tree/arbitrum); this contracts branch uses `block.timestamp`s to count timeouts, instead of block numbers; this also creates a new state for clients (new contracts, new state schema and entry)

### Added
- [#3034] SDK now accepts `config.confirmationBlocks = 0` (default for Arbitrum), speeding up transactions wait times on rollup environments

### Removed
- [#3034] Remove `settleTimeout` option from `config` and `Raiden.openChannel` methods, since this value is now constant per contract deployment (exposed through `Raiden.settleTimeout` getter)

[#2916]: https://github.com/raiden-network/light-client/issues/2916
[#2976]: https://github.com/raiden-network/light-client/issues/2976
[#3034]: https://github.com/raiden-network/light-client/pull/3034
[#3106]: https://github.com/raiden-network/light-client/issues/3106

## [2.2.0] - 2022-04-22
### Added
- [#3069] SDK now can (and will first by default, in `auto` mode) query and use PFS's advertised `matrix-server` before `config.matrixServerLookup`
- [#3068] Try to read `deployment` JSON files at runtime, besides embedded ones at transpilation-time

### Fixed
- [#3100] Filter out registered but misconfigured PFSs used for presence requests which are operating on a different network

[#3068]: https://github.com/raiden-network/light-client/pull/3068
[#3069]: https://github.com/raiden-network/light-client/pull/3069
[#3100]: https://github.com/raiden-network/light-client/issues/3100

## [2.1.0] - 2021-12-29

## [2.0.1] - 2021-12-24

## [2.0.0] - 2021-12-23
### Changed
- [#2949] Allows `Raiden.transfer`'s `options.paths` to receive a broader schema, including `{ route: Address[]; estimated_fee: Int<32>; address_metadata?: ... }[]`, needed to support CLI's `paths` parameter of `/payments` endpoint
- [#2953] `config.gasPriceFactor` applies over `maxPriorityFeePerGas`, using the new fee parameters from London when possible; now, by default, no fee parameters are specified, leaving `ethers` and provider (e.g. Metamask) to figure out best gas fees, fixing [#2952];
- [#2965] Add +5% `gasLimit` margin on transactions which are successfuly estimated, to avoid running out of gas on narrow calls.
- [#3012] Updated raiden-contracts to [v0.40](https://github.com/raiden-network/raiden-contracts/releases/tag/v0.40.0)

### Removed
- [#2965] Remove `options.subkey` on certain `Raiden` public methods; if you need to force subkey or main account usage for single txs, set `config.subkey` then reset after tx is sent; default behavior is kept

### Fixed
- [#2913] Fix crash when starting client with `userDepositContractAddress` as contracts entrypoint on a `TokenNetworkRegistry` with no registered tokens yet
- [#2963] Don't set channel as `closing` upon `channelClose.request`, allowing user to cancel Metamask's prompt and keep an usable channel; Channel becomes `closing` only after tx is sent

[#3012]: https://github.com/raiden-network/light-client/pull/3012

## [2.0.0-rc.2] - 2021-09-14

### Fixed
- [#2798] Delay non-closing auto-settle to prevent wasted gas on channelSettle race; closing side is given priority on auto-settling
- [#2889] Ensure capabilities are updated when they change even if RTC channels are established by reconnecting them.

### Added
- [#2891] Use `TokenNetwork.openChannelWithDeposit` on new contracts for faster open+deposit in a single transaction.
- [#2892] Use `UserDeposit.withdrawToBeneficiary` to withdraw from UDC directly to main account

[#2889]: https://github.com/raiden-network/light-client/issues/2889
[#2891]: https://github.com/raiden-network/light-client/issues/2891
[#2892]: https://github.com/raiden-network/light-client/issues/2892

## [2.0.0-rc.1] - 2021-08-13
### Added
- [#2839] Cooperative settle - allow users to exchange withdraw signatures enabling settling a channel instantly. This is the new default behavior on `Raiden.closeChannel`, falling back to default uncooperative close if needed.

[#2839]: https://github.com/raiden-network/light-client/issues/2839

## [1.1.0] - 2021-08-09
### Added
- [#2766] Add `Capabilities.IMMUTABLE_METADATA` (true on LC, fallback to falsy for backwards compatibility) to allow opting in of not prunning metadata.route and allowing to pass it through mediators unchanged
- [#2730] Add `config.encryptSecret` and `Raiden.transfer`'s `encryptSecret` boolean option, to allow sending secret to target on LockedTransfer's metadata, encrypted with ECIES over their publicKey, skipping SecretRequest/Reveal and speeding up transfers.

### Fixed
- [#2831] Force PFS to acknowledge our capabilities updates
- [#2868] Invalidate routes where some mediator have `capabilities.Mediate=0` and error if this is the only route received from PFS.

[#2868]: https://github.com/raiden-network/light-client/pull/2868

## [1.0.0] - 2021-06-16
### Removed
- [#2571] **BREAKING** Remove ability to join and send messages to global service rooms
- [#2822] **BREAKING** Do not join global rooms anymore, so Matrix-based presence won't work

### Changed
- [#2572] **BREAKING** Send services messages through `toDevice` instead of global rooms
- [#2822] **BREAKING** Presence now gets fetched from PFS and requires a Bespin-compatible (Raiden 2.0) service and transport network
- [#2824] Default Monitoring Service reward increased to 80 SVT

### Added
- [#2822] Added ability to use peer's presence from `LockedTransfer`'s `metadata.routes.address_metadata`

### Added
- [#1576] Add functionality to deploy token networks
- [#2577] Add imbalance penalty mediation fees
- [#2795] Add `config.gasPriceFactor` option, to increase the transactions `gasPrice` as a multiplier of provider-returned `eth_gasPrice`
- [#2813] `open`/`depositChannel` have a new option (`confirmConfirmation`, `true` by default) to wait `+confirmationBlocks` (default=5) after last transaction to give more time for it to be synced on partners and services

### Changed
- [#2669] Update to Raiden contracts `v0.37.5`
- [#2677] Removed the dependency on reactive notifications of peer's presences changes and updated WebRTC signaling algorithm

### Fixed

[#2813]: https://github.com/raiden-network/light-client/issues/2813

## [0.16.0] - 2021-04-01
### Added
- [#1342] Flat (fixed) mediation fees for mediator nodes
- [#1343] Proportional (per transfer amount) mediation fees for mediator nodes
- [#2581] `config.pfsSafetyMargin` now also accepts a `[f, a]` pair, which will add `f*fee + a*amount` on top of PFS's estimated fee, if one wants finer-grain control on safety margin which is added on the transfer to be initiated.
- [#2629] `config.autoUDCWithdraw` (default=true) to allow disabling automatically completing a planned UDC withdraw, and new `Raiden.getUDCWithdrawPlan` and `Raiden.withdrawFromUDC` to check and perform UDC withdraw when not in auto mode.
- [#2644] `Raiden.getUDCTotalDeposit` method to fetch UDC total_deposit, base of `depositToUDC` amounts

### Changed
- [#2536] Wait for global messages before resolving deposits and channel open request
- [#2566] Optimize initial sync and resume previous sync filters scans
- [#2570] Support multiple custom services in config.pfs
- [#2635] **BREAKING** Renamed `Raiden.planUdcWithdraw` to `Raiden.planUDCWithdraw` for consistency
- [#2645] Wait for condition to be ready on `settleChannel` and `withdrawFromUDC` in case it's called early instead of erroring

### Removed
- [#2550] **BREAKING** Remove migration of legacy state at localStorage during creation
- [#2567] **BREAKING** Remove support for peer-to-peer communication through Matrix rooms; now supports only `toDevice` and WebRTC channels.
- [#2600] `wrtc` auto-polyfill; now, if you're using `raiden-ts` in a NodeJS project, you're expected to polyfill `wrtc` or some WebRTC-compatible API to your global object; in exchange, the SDK doesn't require WebRTC, and therefore should work fine on environments without it (through matrix' toDevice messages).

### Fixed
- [#2596] Fix unlocking sent transfers even if receiving is disabled
