# Get withdrawal contract version

`GET /v1/withdrawals/version`

Returns the current version of the rebalancer contracts used for withdrawal signing.
This value should be used as the `version` field in the EIP-712 domain when constructing withdrawal signatures.

**Rate limiting**: 1 request per 6 seconds per client IP. Excess requests receive HTTP `429` with `Retry-After`, `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset` headers (see `RateLimitExceeded` response).

## Response `200`

Withdrawal contract version retrieved successfully

- GetWithdrawalVersionResponse
  - `version` string, required — Current version of the rebalancer contracts used for EIP-712 signing domain

## Other responses

- `401` — No authorization header provided
- `429` — Too many requests for this endpoint. Limits are enforced per client IP for the public API routes backed by `RebalancerResource` (and related resources using the same filter). Response headers (when throttled): - `Retry-After`: seconds to wait before retrying (matches the rate-limit window duration for that endpoint). - `X-RateLimit-Limit`: maximum requests allowed in the window (e.g. `1`). - `X-RateLimit-Remaining`: remaining requests in the window (`0` when throttled). - `X-RateLimit-Reset`: Unix timestamp (seconds) when the limit window resets. `internalCode` in the JSON body is `THROTTLE_PER_IP` for IP-scoped limits (other values may apply for different scopes in the backend).
- `500` — Internal server error
