Equity tiers and rate limits are put in place to prevent spam on the orderbook and prevent the blockchain state from getting too large which can potentially impact performance. For the latest numbers on rate limits, check the dYdX V4 docs here
What are equity tiers?
As part of the default settings of the v4 open source software (”dYdX Chain”), equity tier limit defines the set of equity tiers to limit how many open orders a subaccount is allowed to have.
For example with 20 USDC in equity value, a trader can have 1 open order, with 100 USDC, they can have 5 open orders and so on, according to the table below.
Order Type | Net Collateral | limit |
Long-term or
Conditional orders
| < $20 | 0 |
| >= $20 and < $100 | 4 |
| >= $100 and < $1,000 | 8 |
| >= $1,000 and < $10,000 | 10 |
| >= $10,000 and < $100,000 | 100 |
| > $100,000 | 200 |
Equity Tiers and Isolated Positions
Each isolated position is individually subject to equity tier limits. Therefore, to open an isolated position via a long-term order, there must be at least $20 USDC of margin backing the position. If the isolated position has <$20 of margin backing it, its long term/conditional orders will fail.

What is the Block Rate Limit?
The block rate limit defines the maximum number of CLOB specific operations per block. For example, with short-term orders a trader can place 200 order attempts per block, for stateful orders the limit is 2 per block or 20 per 100 blocks.
Place Orders Type | Num_blocks | Limit |
Short-term | 1 | 200 |
Long-term or Conditional | 1 | 2 |
Long-term or Conditional | 100 | 20 |
Cancel Orders | Num_blocks | Limit |
Short-term | 200 | 1 |
Long-term or Conditional | unlimited | 1 |
How are liquidity tiers and block rate limits determined?
The equity tiers and block rate limits were initially defined in the genesis file of the v4 open source software (”dYdX Chain”). However, the applicable governance community has the ability to create and modify equity tiers and block rate limits as well as update existing placements.
