In Daniel Larimer’s post, “A Three-Step Plan For Lowering EOS Account Creation Costs” he outlined the following.

Step 2 — Lower Account Memory Usage

The default EOS blockchain hard-codes a RAM usage of 3 KB per account where 1.5 KB is currently reserved for future expansion. This was an overly conservative estimate. Upon closer auditing of actual RAM usage per account, we have concluded that only 512 bytes are required for each new account. will provide an update to the system contract that will create 1.5 KB of RAM per account and retroactively offset the overly conservative usage estimate.

This is supported by the GitHub issue here.

EOSIO v1.2.1

On Sep-06–2018 at 13:36:41 UTC, EOS New York approved EOSIO contract update v1.2.1 along with 14 other Block Producers.

Part of this update reduced the cost of account creation on EOS by 25% by making a hard-coded change to how each account calculated the total amount of RAM it had available and added 1400 bytes to all new accounts.

The Path to Adoption

EOS account creation cost is an extremely important aspect of the health of the platform. Many users of EOS decentralized applications (dApps) are early adopters, people who are eager and willing to spend the time to understand the EOS blockchain. But in the future, users will not be as eager. The users of the future will want to use the new dApp they found as quickly as possible. In fact, they may not know they’re about to interact with a blockchain at all.

For that to happen, dApp developers will need to pay for the network resources required to onboard users (or pass this cost on to users). Reducing this cost by 25% dramatically reduces the barriers to development when considering account creation at scale.

Created Accounts

If you are someone who created their account before the EOSIO v.1.2.1 update you are still eligible for the free 1400B of RAM. If you perform any of the following actions you will receive the 1.367188 KiB (1400 bytes): BUYRAM, DELEGATEBW, UNDELEGATEBW. In popular wallets, this is staking your tokens for any of the network resources.

1 KiB was bought however as you can see 2.353516 KiB.

The New Cost of Account Creation

The minimum amount of RAM you should purchase for a new account is now 3KiB or $1.84 (with the free 1400B) as of Sep-06 2018. This new account will be able to hold EOS tokens and up to 8 unique dApp tokens that utilize the token contract.


Please note that these numbers are for testing purposes only. The EOS cost per KiB shown is from an internal test net and does not reflect actual costs. The ram_usage shown does reflect actual ram usage on the EOS mainnet.

This shows the total amount of RAM purchased for a new account that purchases 4KiB of RAM.

4KiB cost 0.0595 EOS

0.595 / 4 KiB= 0.014875 EOS/KiB

Actions taken:

  • eosio tranfers ‘10000.0000 EOS’ to newacct12353
  • newacct12353 transfers ‘1.0000 EOS’ back to eosio

RAM cost for storing tokens = 3574–3446 = 128 bytes

In 1.1.0 the min RAM requirements is 3574 bytes (since we cannot easily get that granular with the purchased RAM we will round up to 4KiB.

This shows the total amount of RAM purchased for a new account that purchases 3KiB of RAM.
