Real user on a fresh install reported TRX and USDT-TRC20 never
appearing anywhere in the Tokens list (not "zero balance", genuinely
absent - including from the multi-chain USDT chain picker). Traced
the full pipeline; every layer up to and including
TypeBasedAssetSourceRegistry, ChainRegistry, address derivation, and
TronGridApi wiring was already correct.
Root cause: pollingBalanceFlow() had no retry around fetch() - any
single transient failure (DNS hiccup, timeout, momentary connectivity
loss during app cold start) threw out of the `while(true)` loop,
killing the flow permanently. The collector
(FullSyncPaymentUpdater.syncAsset()) only logs and gives up on
failure, it doesn't resubscribe. Since the asset's first balance
write never happens, AssetCache never inserts a DB row for it, and
every UI surface (main list, multi-chain picker, search) reads
exclusively via an INNER JOIN that requires that row to exist - so
the asset is invisible everywhere, permanently, with zero
user-visible error.
Swallow fetch() failures and retry on the next interval instead of
letting them escape the loop - one bad poll no longer blackholes the
asset for the rest of the app session.
Also fixes a related but separate gap found while tracing this:
RealSecretsMetaAccount.multiChainEncryptionIn() had no isTronBased
branch (only isEthereumBased), unlike DefaultMetaAccount's
hasAccountIn/accountIdIn which already handle Tron correctly. This
didn't cause the missing-tokens bug, but would have broken "export
account" (JSON key backup) for Tron - fixed by routing Tron through
MultiChainEncryption.Ethereum, matching what
RealTronTransactionService already does for actual transaction
signing (same secp256k1 keypair).
Doc comments describing "/wallet/*" endpoints were parsed as opening
a nested block comment (Kotlin block comments nest, unlike Java/C),
leaving the outer KDoc unterminated - not just a lint nit, ktlint
flagged these as invalid Kotlin files. Reworded to drop the trailing
"*". Also wraps two over-long function signatures/calls.
Reuses the existing generic fee-sufficiency validation
(sufficientTransferableBalanceToPayOriginFee) and send flow
unchanged. Transaction construction goes through TronGrid's own
createtransaction/triggersmartcontract endpoints (verified live
against Shasta testnet) rather than a hand-rolled protobuf
implementation; signing reuses the existing secp256k1 path
(SignerPayloadRaw.skipMessageHashing) already used for Ethereum,
no new crypto library. Also fixes a Phase 1 gap: Chain.isValidAddress()
had no isTronBased branch, so every Tron send would have failed
address validation.
No Energy staking/delegation/rental UI - only Tron's default
protocol behavior (burn TRX to cover Bandwidth/Energy shortfall).
* Add read-only Tron (TRC20) chain family support
Adds Tron as a third chain family alongside Substrate and EVM:
address derivation (BIP44 coin type 195, secp256k1 reused from the
existing Ethereum path, Base58Check encoding), TronGrid-backed TRX
and TRC20 USDT balance display, and a Room migration for the new
per-account Tron key/address columns. Read-only only — no send,
signing, or broadcast support yet.
* fix: exhaustive when branches for Trc20/TronNative asset types
ChainExt.kt's onChainAssetId and Common.kt's existentialDepositError
both switch exhaustively over Chain.Asset.Type and didn't have cases
for the new Trc20/TronNative variants, breaking compilation. Trc20
mirrors EvmErc20 (contract address as the on-chain id, dust burns
rather than transfers on removal); TronNative mirrors EvmNative.
