…3692)

Third batch of the SPL backfill for Solana-supporting canonical wallet
rows not covered by #3669/#3681, based on primary provider documentation:

- okxwallet: OKX Learn pages document OKX Wallet SPL Token Support
  ('OKX Wallet handles both Ethereum and Solana'; support table lists
  'SPL Token Support: Yes'); Solana Compass: 'hold SOL and SPL tokens'
- tangem: tangem.com blog 'Token compatibility: ERC-20, BEP-20, SPL
  (Solana), TRC-20'; help center lists Solana among custom-token networks
- zerion: zerion.io homepage ('Transaction history across EVM and
  Solana'; 'integrated Solana'); Google Play listing documents Solana
  SPL token support (USDT, USDC, BONK, JUP, RAY, PYTH on Solana)

Same root cause as #3660/#3669/#3681: these rows are referenced by
listings/specific-networks/solana/wallets.csv via !offer:<slug>.

No other columns, rows, or files touched. Validation (json-tools
validate_csv, csv_to_json, validate) passes.

* data: add SPL token standard to remaining Solana-supporting wallet offers

Fourth batch of the SPL backfill for Solana-supporting canonical wallet offers, not covered by #3669, #3681 or #3692:

- `1inch`
- `atomic-wallet`
- `coin-wallet`
- `cypherock-x1`
- `ecoin-wallet`
- `frontier`
- `fxwallet`
- `gem-wallet`
- `holdstation`
- `keystone-3-pro`
- `talisman`
- `trezor`
- `zengo`
- `zengo-pro`
- `zypto`

15 cells in `references/offers/wallets.csv`. No other columns, rows, or files touched.

## Evidence (primary provider docs)

| Wallet | Source | Quote |
|---|---|---|
| `1inch` | 1inch.io/wallet | Solana added to 1inch Wallet (2025-06-30); supports SOL and SPL tokens |
| `atomic-wallet` | atomicwallet.io + Solana Compass | Browser extension ships native Solana support: SOL, SPL tokens and NFTs |
| `coin-wallet` | coin.space/solana-wallet | Official Solana wallet page lists SOL and SPL token support |
| `cypherock-x1` | Cypherock release notes | Firmware v0.6.1793 adds SPL token support |
| `ecoin-wallet` | ecoinwallet.org/solana-wallet | v1.7.1 Solana integration with SPL token support |
| `frontier` | frontier.xyz | Solana listed among supported networks (35+ chains) |
| `fxwallet` | fxwallet.com + Solana Compass | Native support for SOL and SPL tokens |
| `gem-wallet` | docs.gemwallet.com | Full SPL and SPL Token-2022 support |
| `holdstation` | docs.holdstation.com + App Store v5.7 | "Solana Support - manage Solana (SOL) and SPL tokens"; Solana listed as Non-EVM |
| `keystone-3-pro` | Solana Compass | Manage SOL, SPL tokens and NFTs; Solflare integration |
| `talisman` | docs.talisman.xyz | "Solana, Substrate, and Bittensor networks and token balances are automatically enabled" |
| `trezor` | trezor.io | Solana and SPL support; Suite adds Token-2022 (2025-01) and native staking (2025-03) |
| `zengo` | zengo.com | "Send and receive SOL and SPL tokens" |
| `zengo-pro` | zengo.com/pro | Pro tier shares the same engine; Solana/SPL support |
| `zypto` | zypto.com | Full SOL and SPL token support with Raydium DEX integration |

Same root cause as the Phantom correction in #3660 and the #3669/#3681/#3692 backfills: these canonical rows are referenced by `listings/specific-networks/solana/wallets.csv` via `!offer:<slug>`, so the missing SPL standard propagates as inherited data to every network listing referencing these wallets.

## Deliberately not included

- `haha-wallet`: vendor copy is contradictory (App Store states "Ethereum and Polygon networks supported" while also listing Solana), so it needs a clearer primary source before claiming SPL.
- `metamask`, `base-wallet`, `ctrl-wallet`, `wigwam`, `pillar`, `clave-wallet`: still under verification.
- `kuma-wallet`, `taho`: these do not support Solana (EVM / Polkadot-ecosystem only) and appear mis-listed on the Solana page; reported separately instead of being given SPL.

## Validation

- Surgical edits verified programmatically: 15 changed cells, 0 off-target cells.
- Row count unchanged at 106; only the `tokensSupport` column was touched.

* data: add SPL token standard to MetaMask offer

MetaMask ships native Solana support, so its canonical row needs the SPL
token standard alongside its EVM standards.

Evidence:
- MetaMask Support, "Navigate Solana in MetaMask": "MetaMask supports Solana,
  allowing you to manage your SOL and SPL tokens alongside your EVM-supported
  (Ethereum) assets."
- Consensys blog, "Native Solana support in MetaMask accelerates new era of
  multichain access": users can "seamlessly manage Solana and SPL tokens,
  including sending, receiving, swapping, bridging, and onramping assets".

1 cell in `references/offers/wallets.csv`. No other columns, rows, or files touched.

Rewards address: 0x2409b47a530be3831158f10b08ac93f7d08c1ff2

* data: add SPL token standard to Wigwam and Base (Coinbase Wallet) offers

Both wallets ship Solana support, so their canonical rows need the SPL token
standard alongside their EVM standards.

Evidence:
- Wigwam (official, https://wigwam.app): "Wigwam is a free crypto wallet that
  supports the most common EVM blockchains and Solana from the box"; FAQ: "The
  Wigwam app supports all tokens issued on EVM blockchains and Solana."
- Coinbase (official blog, Solana support announcement): "Coinbase Wallet
  extension users can store, send, and receive Solana (SOL) and all of its SPL
  tokens alongside all of their EVM-compatible assets" -- Coinbase Wallet is the
  product now shipped as Base App / Base Wallet.

2 cells in `references/offers/wallets.csv`. No other columns, rows, or files touched.
