Maker (MKR), the governance token of $5.3 billion decentralized finance (DeFi) lender MakerDAO, surged to near a one-year high price Friday following the introduction of a token buyback program.

MKR briefly rose above $1,200 early Friday for the first time since last August, then pared some of its gains to change hands at around $1,144. The token is up 28% over the past week, significantly outperforming the 4.6% decline of the CoinDesk Market Index, which tracks the broader crypto market’s performance.

The price action occurred as the lending protocol activated a token buyback scheme on Wednesday, removing MKR supply from the market. The so-called Smart Burn Engine periodically allocates excess DAI stablecoins from Maker’s surplus buffer to purchase MKR from a UniSwap pool, a governance proposal explains.

The program was deployed earlier this month, and it went live Wednesday once the surplus buffer exceeded $50 million.

In the last 24 hours, the protocol bought back some $230,000 worth of MKR, according to blockchain data by Etherscan. At this pace, the protocol is on track to purchase about $7 million in tokens in the next month.

The token’s total market capitalization is about $1 billion, so the buyback would reduce 0.7% of the supply per month at current prices.

Maker is one of the largest and oldest DeFi lending protocols, and also issues the $4.6 billion DAI stablecoin. It is led by a decentralized autonomous organization (DAO), in which MKR holders vote on governance proposals.

The protocol has been increasingly investing DAI’s reserve assets in traditional investment products such as bank loans and government bonds to earn revenue from yields. MakerDAO also is undergoing a major overhaul that includes upgrading the DAI and MKR tokens, and breaking up its structure into smaller, autonomous organizations called SubDAOs that could issue their own tokens.
