Both registers are optional. Without a borrower register, the collateral token's own compliance alone governs borrowers. Without a provider register, each vault admits depositors through its own register alone. Change the registers with [Set Identity Gates](/endpoints/lending/set-identity-gates). ## What Each Register Gates On a current market, the two registers gate different parties at different doors. The **borrower register** (`borrowerRegistry`) is examined by the market itself on every `openLoan` and `borrowMore`. Repaying, closing a loan, releasing collateral and claiming a surplus are never gated. The **provider register** (`providerRegistry`) is not examined by the market. The market takes direct deposits only from the operator wallet and the vaults its admin registered, and asks no register about either. Every registered vault reads the market's provider register, beside its own register, before it admits a depositor or a share transfer. With no provider register, each vault admits depositors through its own register alone. Redemptions are never gated. Every check is a live `isVerified(address)` call against the register, so a change on the register side takes effect on the next call. Registers answering a single `bool`, as ERC-3643 and ONCHAINID-based registers do, and registers answering `(bool, uint8)`, as the Trusset register does, are read alike. A register that cannot answer refuses every party. ## Older Market Generations `generation: SINGLE_REGISTER` marks an earlier implementation that examines borrowers and providers against one register and offers no way to change it. `providerRegistry` then repeats `borrowerRegistry`, and `upgradeRequired` is `true`. The market admin moves it onto the current implementation with [Upgrade Market](/endpoints/lending/upgrade-market) before the registers can be chosen. A two-register market from before the current generation reports `vaultOnlyLiquidity: false` and `providerGateReadBy: MARKET`. When its pool is open to third-party providers (`operatorOnlyLiquidity: false`), the market itself examines those providers against the provider register, which must then stay installed (`providerGateRequired: true`). ## Path Parameters Market ID. ## Response Fields The market, lowercased. `TWO_REGISTERS` on an implementation with independent borrower and provider registers, `SINGLE_REGISTER` on the earlier one. Whether the registers can be changed through [Set Identity Gates](/endpoints/lending/set-identity-gates). `true` exactly when `generation` is `TWO_REGISTERS`. `true` on a `SINGLE_REGISTER` market, which has to be upgraded before its registers can change. `true` while the market has no lender of record, and so no admin who could change the registers. `MARKET`, `NAV` or `ORACLE`. The borrower register, lowercased, or `null` when none is installed. The provider register, lowercased, or `null`. On a `SINGLE_REGISTER` market it repeats `borrowerRegistry`. Whether the pool is closed to third-party providers. Always `true` on a current market. `true` on a `MARKET`-priced market, which must keep a borrower register. It cannot be cleared. `true` only on an older market whose pool is open to third-party providers. Always `false` on a current market. `true` on the current generation, where the market takes direct deposits only from the operator wallet and registered vaults. `VAULTS` when the registered vaults read the provider register, `MARKET` on an older market that reads it itself. How the borrower register answers. The register, or `null`. `none` with no register, otherwise `bool` or `tuple` for the answer shape it gives. `unknown` means it was reached but does not answer `isVerified(address)`; `unreadable` means it could not be reached. Whether the register answers in a shape the current implementation reads. `true` for `none`, `bool` and `tuple`. The same three fields for the provider register. Identical to `borrower` when both name the same register. ```bash cURL theme={null} curl "https://api.trusset.org/lending-external-securities-v2/api/markets/{marketId}/identity-gates" \ -H "X-API-Key: trusset_your_key_here" ``` ```typescript TypeScript theme={null} const res = await fetch( `https://api.trusset.org/lending-external-securities-v2/api/markets/${marketId}/identity-gates`, { headers: { 'X-API-Key': 'trusset_your_key_here' } } ); const { data } = await res.json(); ``` ```json Response theme={null} { "success": true, "data": { "marketAddress": "0x70a0e25c7b768b87e658348b3b577678a173e038", "generation": "TWO_REGISTERS", "adjustable": true, "pendingCurator": false, "priceSource": "NAV", "borrowerRegistry": "0x4f2a9c81d06e3b75a1c8e24d9b07f56e3a1d8c90", "providerRegistry": "0x7d31e6b09a4c25f8e1b73d0a6c94e2f58b1a0c37", "operatorOnlyLiquidity": true, "borrowerGateRequired": false, "providerGateRequired": false, "vaultOnlyLiquidity": true, "providerGateReadBy": "VAULTS", "borrower": { "address": "0x4f2a9c81d06e3b75a1c8e24d9b07f56e3a1d8c90", "shape": "bool", "usable": true }, "provider": { "address": "0x7d31e6b09a4c25f8e1b73d0a6c94e2f58b1a0c37", "shape": "tuple", "usable": true }, "upgradeRequired": false } } ``` ```json Response - Earlier Implementation theme={null} { "success": true, "data": { "marketAddress": "0x70a0e25c7b768b87e658348b3b577678a173e038", "generation": "SINGLE_REGISTER", "adjustable": false, "pendingCurator": false, "priceSource": "NAV", "borrowerRegistry": "0x4f2a9c81d06e3b75a1c8e24d9b07f56e3a1d8c90", "providerRegistry": "0x4f2a9c81d06e3b75a1c8e24d9b07f56e3a1d8c90", "operatorOnlyLiquidity": true, "borrowerGateRequired": false, "providerGateRequired": false, "vaultOnlyLiquidity": false, "providerGateReadBy": "MARKET", "borrower": { "address": "0x4f2a9c81d06e3b75a1c8e24d9b07f56e3a1d8c90", "shape": "tuple", "usable": true }, "provider": { "address": "0x4f2a9c81d06e3b75a1c8e24d9b07f56e3a1d8c90", "shape": "tuple", "usable": true }, "upgradeRequired": true } } ``` ```json Error - Unreadable theme={null} { "success": false, "error": { "code": "IDENTITY_GATES_UNREADABLE", "message": "The market registers could not be read from the chain.
